Trolls Go Round And Round

What appears to be the one absolute and unsurprising fact in this industry — someone is always out to try to take a bite out of you. Or try to get their friends to come after you so they are not seen as participating. What is surprising (or maybe amusing?) is how they like to come at you at times. It would be a much more entertaining read if they had some understanding about the things they were frantically smashing into their keyboards. Unfortunately — it’s quite clear they have little to no experience in anything but slinging mud. I cannot help but just shake my head and go back to helping my customers paying for my time.

Fortunately, I had the time and opportunity to bring up a few examples — had a 2014 Civic Si on the dyno to tune and it turned out to be a chance to touch base on the results of tuning a stock 9th gen Civic as I still get asked about it a lot.

Oh That VTC Mapping Is Such Shit!

This one really gets me. When someone doesn’t understand why something in a tune was done the way it was — it’s clearly shit. Their first reaction is to grab their pitchforks and torches when it should be to pause and analyse why something was done the way it was.  I see this attitude frequently and can only wonder if someone like this would ever take any advice or constructive criticism thatuned_vtct could help? If something is truly “shit”, lay out why in intelligent fashion — and no, not just a dyno sheet or 3hp. Or switching gears on the dyno and claiming you made power with your “tune” when all you’ve done is introduce another variable that just made any use of the baseline invalid. We’ve made 6hp on some 9th gens just by letting it sit and cool off . Not even the best troll attempt I’ve seen — but cute, I guess?

A truly good example is a tuned VTC map — particularly the low cam (non-VTEC). Low cam was tuned to determine the best cam advance, and then high cam was tuned to determine the best cam advance. Finally the transition was optimized to provide the best curve possible when going into VTEC during a full throttle pull. Optimal power at 5000 rpm out of VTEC was with 5* VTC — however it was 35* VTC in VTEC at 5000 rpm for optimal power. So what happens when VTEC engages and you have such a large VTC transition? The VTC system is still at 5* and the motor makes less than optimal power until the cam has a chance to move to 35* VTC. As a result the transition was optimized by a very short and quick snap from 8* at 4900 rpm to 32* at 5000 rpm while VTEC is still off — a very smooth transition when at WOT and no loss of power is seen or felt. If you don’t see this difference on tvtec_diphe dyno — time to replace your piece of shit roller (hah, I just went there).

What does this look like on the dyno? The graph at the left illustrates this. Solid lines are horsepower and torque with the VTEC “pre-phasing” trick done, dashed lines are without. Pretty obvious torque dip at VTEC, right?

Wait, if this is so good, why are you telling everyone about it? Because this is not a secret. When the K series first came out Hondata pioneered this trick and published it publicly for EVERYONE to use. The irony here is — very few use it, and even less understand why. It’s a better idea to just go on the Internet and make it obvious you’ve done like two Honda K series vehicles and now you’re an expert? More like wet behind the ears.

Hold on, it gets better… you know even *Honda* uses this trick now? Juhonda_vtcst look closely at the stock Honda 9th gen tune. For the two seconds it takes to see it — it’s not tough. They didn’t use this on the RSX’s or the 8th gens — and their use of it is very subtle on the 9th gen.

I’ll be Mr. Nice Guy — to the right is the stock 9th gen VTC map. Note the values at 5000 rpm at full throttle — they go back up slightly in anticipation of the VTEC crossover (which is 25 at 5000 rpm in VTEC on the stock Honda tune) — the only difference is they didn’t use a 4900 RPM break point as they really don’t care if the car loses 4hp across 500 rpm worth of power from running 7-9 degrees too much VTC (I guess they haven’t met the experts on the internet yet?). Yes, Honda intentionally mapped the motor this way — there is absolutley no reason to bring the VTC back up in an area it naturally wants to taper down to keep making power on the low cam.

Shocking, I know.

I Did Such And Such And Made More Power


Let me repeat.


Tuning is about so much more than making power. I have customers with 150k+ miles on their turbo vehicles. I also have a dyno at the shop readily at my disposal. I know what makes power — in fact I use the dyno not only for tuning customer’s vehicles and builds at the shop, but as an R&D tool and apply what I discover into our eTunes to help deliver reliable cars for customers around the world.

Part of tuning is making decisions and judgement calls that will ultimately determine a setup is reliable long term — or not. In varying conditions year round — that the tune has to take into consideration and adjust for. This is why people go to reputable and experienced tuners, instead of a random guy offering you tunes for $50? Right? Maybe I’m wrong, what do I know?

So About That Stock 9th Gen?

I’ve posted several comparisons of stock 9th gens. I always answer — yes there are benefits, it will make a bit more power, and the power will be more consistent.

Here is the simple and visual example of this. The engine coolant temps (ECT) where 185-188 degrees F and intake air temps were 59-60 degress F on the stock tune baselines. Yes, I made sure these were consistent to avoid any extra variables when doing the comparison — if you’re paying someone 60 bucks for 3 baseline pulls I can tell you with absolute certainty they are not paying attention and simply don’t care. Yes it does matter — I’ve had customers datalog their baselines and in some situations there’s not even a dyno fan on the car — I’ve seen 20-30 degree difference in ECT (180 and 210…) and even a 30-40 degree swing in air temps between pulls. If someone thinks it “doesn’t matter” — they should not claim to be any kind of EFI tuning specialist.

Astock_comparisonnyway… stock pulls. Three pulls with consistent conditions. Left graph is torque, right graph is horsepower. Quite the difference on the top end right? 10-12 HP swing in some spots. Yes, the stock Honda tune is very inconsistent in it’s power delivery — and no it is not the “knock control” as some would make you believe. The simple answer is just this: emissions.

Ncomparisonow four (yes four) pulls with consistent conditions — 185-188 degree ECT and 68-70 degree IAT. A negligible .5-1.2hp swing. Virtually nothing. This is on a dyno that is accurate to .1hp (no, a roller dyno does not nearly have this kind of accuracy — having a wheel/tire on the car can cause a 2-4hp swing).

finalAnd as every tuner in the world loves to do and not tell everyone… we overlay the highest “tuned” graph with the lowest “baseline” graph. This behavior should come as no surprise — as a ton of “tuners” make a living off nothing more than the way their dyno reads (big numbers sell tunes and that means you’re the best right? Hm… I’ve got some graphs I can post… no, I probably shouldn’t go there).

final_bestWhat’s it look like if you overlay the best “tuned” and the best “baseline”? Pretty good gains still.

And now I’ve run out of thinks to rant about…

Toyota Celica GT/GT-S Tuning on the AEM Infinity

For a little change of pace I want to discuss the AEM Infinity retrofit we did on a customer’s Toyota Celica, what really prompted this change and the features of the AEM Infinity we implemented on this platform — as well as a few others that are available.

The Background

We had the customer’s car in the shop for a fair amount of time — installing the Monkey Wrench Racing turbo kit he had purchased with the engine management package. The turbo kit did require quite a bit of customization to fit, but we took care of all that and the car was ready to tune.

I spent a good 3 weeks on the stand alone ECU that was included with this package as I was never quite content with the drivability of the vehicle with the included engine management. I don’t want to name any names, but it is the “accepted go-to” EMS for this platform — with fairly hefty price tag (customer paid something like $1500 for it). Unfortunately it is not a very good EMS and is very dated — it’s comparable to running something like an AEM V1.

Did the car make power? Sure — it’s not hard to make power. However this EMS was plagued with random misfires and quite a bit of time was spent chasing the misfires (hardware, coil dwell, sync, etc) and eventually they became very rare — but not quite gone. When taking the car off the dyno and on the street no misfires were apparent — I’ll get into that more later.

After the car was off the dyno, I put in a week of street tuning for drivability — cold start, cold start driving, warm start, warm start driving, the works. The transient response that was achieved with this EMS was not remotely what I would call “great” — warm or cold. Many would consider it to be “acceptable”, but in my book if the car doesn’t put a smile on my face from the moment I fire it cold and tear off down the street without giving me weird moments of hesitation — it’s simple crap. Why? Because I work with dozens of different EMS and dozens of different platforms — I have a very intimate understanding of what “great” drives like.

And before people start questioning — yes, all the cold start, post start, throttle pump, throttle enrichment, delta tables were tuned, every single parameter that was exposed was tuned to try and improve overall drivability.

Finally we had no choice but to let the customer try the car out and see what he thinks — and we went in not at all happy with the results this EMS let us achieve.

So What Now?

Sure enough, he brought us the car back a week later as agreed to let us fit a much more modern and advanced EMS on the car — an AEM Infinity.

Before I go into the details of this EMS, let’s go into what we expect to be able to do with our EMS and how it compares to what the previous EMS (these are some basic features as this car was run at 10psi on wastegate — no boost control):


As can be seen, the basic features look quite similar (the AEM Infinity is capable of much more — including traction control and DBW), so why would the Infinity be so much “better”? Let’s look into a few bullet points.

The Misfire Issues

This is the most annoying part of the previous EMS — once we retrofitted the AEM Infinity on the vehicle, we did not experience a single misfire. The AEM was sync’d and tuned without experiencing a single misfire during the tuning session. This leads me to believe the previous EMS was having trigger sync issues and/or problems running the coils/injectors. The coils & injectors themselves were not a problem (and neither were the cam/crank sensor) as they all functioned perfectly on the AEM Infinity.

VVT-i Control

A picture is worth a thousand words. Yes it works with the AEM Infinity — just requires proper install & configuration. Not a “big deal” to get it working. And the feedback/control is completely adjustable.


Closed Loop Fuel Control

This was extremely lacking on the previous EMS — in fact I’ll go so far as to say it was completely junk. When you’re paying $1200 or more for an ECU you would expect a modern EMS to have wideband O2 control already without having to pay extra and depending on a narrowband O2 sensor — which amounts to slow feedback and inaccurate feedback (fueling swinging back and forth, etc).


As you can see, with the AEM I configured feedback well into boost (in fact the system is so fast and accurate you can run it full time on high boost applications as well).

The previous EMS? It simply didn’t have this ability — and I wouldn’t trust it using an analog input into the ECU. It’s not accurate and the EMS has no control over the O2 sensor directly (since it requires a separate controller) — so if the sensor has a fault the EMS would know. The AEM *does* control the O2 sensor and is very quick to detect a fault (from experience), and you can chose to put the ECU into protect mode if the sensor faults. Fantastic.

Knock Control

Two words: It works. Here’s a short clip from the street tuning session with the AEM while I was out touching up the car (IE: drivability adjustments, finding any spots it may knock with “real” load on the car on the street).


This is just a small glimpse at the control — we also have the option to enrich lambda during knock events and individual cylinder knock thresholds.


This was a real source of frustration with the previous EMS — 8 channels of datalogging (and not real time at that — you have to record and then view) is horrible. To use the term “unacceptable” is an understatement — the more data you have to view the better you can tune the EMS and you get a much better picture of what the EMS is doing if you have to do any diagnostics. Not enough data and you can be left chasing your tail — at the very least it takes up much more of your time as you’re stuck with scenarios of “oh I wish I had logged that parameter… but all 8 channels are already used..”.

The AEM lets you record everything. And the “on board” datalogging is expandable by the size of the USB drive you plug into it if you need “on board” datalogging. The fact an EMS company advertises “256K” of onboard datalogging is just laughable — that’s NOTHING and utterly useless (not enough data, or not enough data at meaningful refresh rates).


This was the biggest point of annoyance for anyone driving the car previous — the throttle response, transient response and drivability just wasn’t there with the previous EMS. Sure if you had a race car, you put your foot down and it worked fine. However with the new AEM Infinity installed and tuned (which I might add only took two days to fully tune on this vehicle — yes you read that right) the drivability of the vehicle soared to perfection.

No I’m not exaggerating — I could fire the car up cold or hot and stab the throttle immediately without any delay or hesitation. Off I went down the street to do further fine tuning.

The best part? I was able to deliver the car to my customer driving perfectly in every scenario. Awesome.

So What?

I guess what I can say about the faults of the old EMS lie in a couple of points.

  • Old outdated hardware.
  • Poor software — on the EMS and desktop (yes the software does matter).
  • The fuel film model in the EMS was basically non-existent or poorly modeled — this caused our drivability issues/concerns.

Does that EMS look good on paper? Mostly, yes. But looks and practice can be completely different things.

Why is this old EMS so popular? I think this mostly comes down to what select groups have learned and push adamantly on this platform — simply put they are stuck in their ways and either don’t know anything better or don’t want to try anything that could be better. It “works for them”, as I hear a lot.

However if you are looking for something better on this platform that can improve your vehicle — we have better options available that don’t break the bank.

The Tooner Phenomena

Now I am sure this is going to ruffle some feathers and some might even dust off their pitchforks — so be it. It has to be said — living and breathing cars, modifications and tunes day in and day out you see some outrageous things come your way. I am going to break it down into two simple categories — food for thought and enthusiast beware.

The Expert Tooner

This is the guy that has a shop or works for a shop — they have a dyno and you would think they would know how to use it. In fact, some of them do know how to use it very well, and the break down begins with the fact they understand very little, if nothing at all, about EFI tuning and/or the engine management software they are using. Hell, they might even be working at a shop that has a stellar reputation!

They are able to post up amazing numbers on said dyno, but the vehicle will just run terrible either the moment it leaves, or a couple days later. When the car comes back to them — they cannot figure out the source of the problem and will at times chase mechanical gremlins that do not exist.

One prime example of this is a customer with a 2012-2015 Civic Si — said customer had some work done at his location and the vehicle posted up absurd power figures on pump gas (93 octane) — nearly 500hp. Anyone who has any experience with that platform will raise an eyebrow — maybe it’s possible? Highly unlikely with how knock prone those motors are. But hey, the customer was initially quite happy with the numbers — and then the bad news. After a couple of days the car would be completely gutless, and any attempts to have that behavior remedied kept failing.

He finally got a hold of me and we went over what was going on — turns out he was an existing customer of mine that had a tune for his car whnegative_timingen it just had bolt ons. After reviewing his turbo datalogs, it turns out it was running 17-18psi of boost and -2 to -6 degrees of timing (yes, NEGATIVE). It doesn’t take a rocket scientist to figure out this does NOT make power. In fact — it makes about a whopping 200 horsepower with all that boost, not anywhere NEAR the claimed dyno figures.

And yet it continues to get worse — part throttle closed loop feedback was disabled, the primary O2 sensor completely disabled, VTEC point untuned, VTC mapping completely untouched. No excuse for any of these items to be the way they were — so where was the break down? Upon inspection of the actual calibration — the tune file was basically nothing more than the calibration for his vehicle with simple bolt on parts. Quite literally the injector scalar (how big the fuel injector is) was adjusted and the fuel map was roughly skewed upwards in boost — nothing else in the calibration was setup anywhere close to how a turbo calibration should be done to get a reliably running vehicle. You read that right — he was running MY N/A tune on his car with a turbo. You can imagine how well that works.

So how did it make power on the dyno? Quite simply — with every flash of the ECU its “learned” parameters were reset and under boost the motor was seeing effectively naturally aspirated ignition timing. Wait, won’t this cause detonation? Absolutely — this platform does not have active knock feedback logic, only having a very slowly learned correction (which works poorly on modified vehicles to begin with) and the motor will definitely make power.

So the sum of his “expert” tune was nothing more than a couple of hits on the dyno with a calibration that was ripped (stolen) off the FlashPro when the vehicle came in for work to be done.

But a couple days later — the ECU goes limp mode to protect the engine. In this case — the owner of the vehicle was very lucky. We dialed the boost back to 11-12psi and tuned the car properly and it hasn’t had a problem ever since.

The Noob Tooner

You know who I am talking about here — they are all over social media and online forums. They will make you promises and whisper sweet nothings via private messaging systems to get your attention and make your wallet a little bit lighter. I have seen examples of them even claiming:

  • Tune just like “so-so” (enter tuner name here) for the same amount of $$$.
  • It’ll be just as good or better than “so-so”.
  • “So-so” is terrible and they’re better.

What skills, experience and accomplishments do they actually have? Well it’s quite simple:

  • They purchased a laptop.
  • Downloaded some free software.
  • And in many cases: stole a base file they are now using as their “source of truth”.

Yup — that’s right: all it takes to claim to be a tuner extraordinaire on the internet is a laptop and the ability to transform drivel that would normally flow through their lips into text via their fingers rapidly clacking away at their laptop keyboard.

Even better — in many cases they’ve even purchased a tune for their own vehicle from an established tuner. This has happened so many times I have lost count — I am more than happy to share examples with the reader privately.

But you bet they will be all over the internet trying to snag their next victim — sometimes advertising their services, sometimes trying to stay under the radar and snag their victims via the amazing stories they like to tell via private message.

And at the end of the day — they have little to no experience (you will see stuff like “I tuned my car”, “I tuned all my friends”) and no accomplishments of any kind. Of course they will claim that they “have to start somewhere”. Anyone sign their vehicle up as R&D when they paid for a tuning service?

Amazingly enough — they will always have someone “vouch” for them and their “skills”.

So What?

This is a vicious cycle — I’ve seen it so much that I just shrug and let our business and our work speak for itself.

But be warned — the tooners of the world will throw timeslips, dyno sheets and vouches at you all day long and in their minds it gives them completely credibility. Sure — going fast and big numbers are fun, but it paints a very poor picture of any experience or ability to tune a car properly to do anything beyond that. When you have a vehicle you need to drive day in and day out, there is a lot more that goes into setting up a tune than dyno numbers and time slips.

The goal is to hopefully share some insight with the reader and maybe prevent another case of Tooner Attacks. Ultimately it is up to every enthusiast to do their own research — and I encourage you all to do so.

N/A Bolt On Nissan 370Z E85 Test Results

What I really wanted to title this is “ignorance is bliss — no WAY could ethanol possibly even a single HP over pump gas”. I was inspired to do this test by a very bold claim on a certain online forum — I’ll keep the names out of it, but it definitely gave me a chuckle.ignorance_is_bliss


There are so many faults with this bold claim — but the very first thing any reader should get out of it is that when someone posts something in absolutes like this you should take their statement with skepticism and simply do your own research.

Not a single hp.

Really? The one thing I’ve learned in the 12+ years of tuning ALL kinds of motors, is you simply can’t deal in absolutes. Something may make power that could be taken as “margin of error” for the type of dyno you’re on or just very negligible gains that will never be noticed in the “real world” (say like 2-3hp for example, but it really is relative to the platform, etc — this is a question best left for another discussion).

The irony here is the statement preemptively tries to attack the skills and credibility of anyone doing a pump gas to E85 (ethanol) tune. I can’t say if this is really just the ignorance of the author of the post or just a gigantic ego that blinds him to reality.

My response is simple — “Oh please”. Fortunately for us, there are a few of us that are quite capable at what we do and we have actual tools at our disposal to do quantifiable testing instead of listening to someone spew hearsay on the internet.

Now for the sake of transparency — our pump gas is 92 octane, not 93 octane. However — big deal — the gains from going to 92 octane to 93 octane on a motor that isn’t ignition limited on 92 octane will be minor or nonexistent (and ours wasn’t — I could roll past MBT on the ignition map and not get detonation, there was just no more power to be had — which is what the statement about 91 octane implies). Hey don’t take my word for it — try it yourself.

As for the argument of WHY would E85 have gains over pump gas? What the author of said post seems to miss is the properties of the fuel — it is naturally oxygenated and has much better cooling properties than pump gas (regardless if said pump gas is 91-93 octane). I’ve done hundreds upon hundreds of E85 tunes — N/A or F/I — and I have yet to see a motor that doesn’t gain SOMETHING over pump gas (see what I did there?).

The Test

OK enough with the bull shit — here’s the results and the actual FACTS.

The car is a 2015 Nissan 370Z, with bolt ons:

  • Stillen Intakes
  • G35 test pipes (modified to fit)
  • Agency Power 2.5″ dual exhaust

VVEL and VTC had been previous tuned for this setup on pump gas, and were left alone for the E85 portion.

After the vehicle was filled up with E85 (tank took 16.5 gallons), fueling was pump_vs_e85_fuel_only_wmtuned to maintain a proper air/fuel ratio without touching the timing map — the motor continued to run the same timing curve as it did on pump gas. Simply running E85 and maintaining proper fueling netted us 8whp. Wow, this is already certain more than Not A Single HP. And well above any kind of margin of error.

Next I adjusted the timing map to see if we could extract a bie85_fuel_vs_e85_timing_wmt more power — and 4whp was found. The amount of timing added was very negligible (could run this timing map on pump octane without seeing detonation — it however netted no gains on pump gas), and what we can gather from this is that due to the larger volume of fuel we are injecting with E85, we needed to ignite the mixture a minute amount of time sooner to get a complete burn of the mixture in the cylinder.

e85_all_in_vs_pump_wmWhat does this look like overall? We picked up 12whp and as much as 12wtq through parts of the torque curve. Wow, that certainly looks like it’s a lot more than Not A Single HP. The best part about it all? This is free power — the stock fuel system supported E85 without upgrading anything — we ran stock injectors and the stock fuel pump. And to top it all off — fuel economy during freeway cruising was not impacted at all — if anything it was 1-2mpg better than what I was used to seeing on pump gas.


Really, what should be said about E85 gains on this motor is depending on the quality of your pump gas (because yes, even quality of 93 octane can vary), you may see between 2-4% gain in power with E85. You will also see it through out the whole power curve — more than can be said about the Stillen intakes I tested on this car, which had margin gains through a couple of spots of the power curve. Quite literally the dollar per HP gains from just running E85 (which is readily available at the pump by the shop) surpasses a $560 intake system.

There you have it — quantifiable results vs hearsay (or apparently I have some kind of secret to making power with E85).


Just a Couple Headers and a Slow FT-86: Skunk2 EL vs Tomei UEL

Now I want to get into this and say that I was not in any way displeased with the Skunk2 Alpha race header on our Scion FR-S — the power pick up over stock was significant, and I expected it to maintain a bit of a torque dip being it is of equal length design and we see that dip remain in some form with all the equal length headers.

I have been running this header since it came out on the platform and after helping a few customers with their Tomei unequal length race headers, it really peaked my curiosity and I wanted to do a legitimate comparison. None of this “open two dynos from two different cars” as is so common with the vast majority of “comparisons” being done. It opens a can of worms and seemingly endless debate about this and that.

Some information about the parts and vehicle as it sits now. After spending countless hours testing and tuning the car using ECUTek (which I still offer for customer cars), I have switched it to a MoTec M1 stand alone ECU for it’s advanced features and ability to rapidly tune new configurations on the vehicle (no more “Flash and Wait” — given this car is a test mule, this saves countless hours on R&D and as they say: time is money). This comparison is done with both configurations tuned on the MoTeC.

Other relevant information:

  • Skunk2 Intake
  • Perrin 3″ Exhaust
  • Perrin Over Pipe
  • HKS Front Pipe
  • E85 fuel

The use of E85 fuel makes the vehicle much more consistent and the comparison much more reliable — the correction factor used on a dyno gives you an “estimate” to compensate for weather differences, but it is only an estimate. The use of E85 ensures the motor is able to be run at MBT for ignition timing even if we have a temperature swing — something that cannot be said of 91-93 octane pump gas. From my tests on this vehicle I found a whopping 1hp difference from running E85 in 40*F weather vs E85 in 90*F weather while tuning on the Dynapack. This helps aid in the consistency of the test. With pump gas a pull used for comparison that was done in 40*F can and will make a fair bit more power than a pull done in 90*F, so you really have to be careful when doing parts comparisons on pump gas which can just lead to more debate. That being said, even with the E85 fuel, I went to great lengths to make sure the conditions were pretty much identical between the two tuning sessions.

My Expectations

With the swap to an UEL race header it goes without saying that I expected to flatten out the torque in the area where the dip remained with the EL race header. However, I was also expecting to lose out on top end as this seemed to be the “expected” results between the two styles of header. And so I was about to find out how true this was… Bearing in mind the Skunk2 Alpha is a header I’ve been running for 9 months through many tuning sessions where I’ve eeked out everything there is to be had on this setup.

The Results

So without further ado — the test was simple. The vehicle was fully tuned in great detail with the existing setup — all fuel, timing and cam timing dialed in. As soon as the Tomei UEL was delivered it installed after the Skunk2 was removed and the car went right back on the dyno for more tuning.


I was indeed partially surprised by the results — the story is that EL should have better top end? Doesn’t look like it’s even remotely an accurate statement as not only did the UEL match the EL, it carried torque much better up top and didn’t drop off as soon. The mid range also filled in significantly and the low end was no worse than the EL — unless you count the blip at 2600 rpm. Which I don’t, as that blip is literally nothing more than a blip and I can assure you from driving the car with the Tomei on it, you won’t ever miss that blip, it’s like it doesn’t exist.

For the curious, the data from the two runs (which were about 5 days apart) demonstrates the weather conditions were virtually identical (RemoteTmp, Baro & RelHum).




This was an interesting test, and I’m happy I could fit it in before the car gets torn down for our turbo kit build — yet there are many more items I would love to test. It would definitely please me to have a full “header comparison” database for this vehicle — if I could borrow every header and take a week to test them all out, I would.

As it stands now — the car makes more torque than it did horsepower in stock form, which is quite amusing.


The Nissan 370Z — Testing Bolt Ons & Tuning

It’s that time again — got my hands on a 2015 Nissan 370Z and the typical bolt ons we see on this platform for some tuning and parts testing! As always, I tune the car completely stock first to get a good “tuned” baseline, and then retune after every set of mods. This is a very fun platform to tune due to the very flexible VVEL system.

So what we will have on this test is:

  • Bone stock vs Bone stock tuned
  • Stock tuned vs Full Exhaust (Test Pipes + Exhaust) tuned
  • Full Exhaust vs Intake & Full Exhaust tuned

The parts in question are the following:

  • Agency Power dual 2.5″ exhaust
  • G35 test pipes modified to fit compliments of Old Man Dan’s hack and weld skills (certain vendor screwed up and sent me the wrong parts, I was not amused)
  • Stillen V3 long tube intakes

So without further ado, here we go.

Stock vs Stock Tuned

stocktunedIt was pleasant to see there was actually a fair bit of room to improve over the stock mapping on the ECU — especially with the refined ignition control available to us now. One of the nuances I was able to fix was the throttle closer on the top end and the delayed throttle opening on the low end the stock ECU exhibits — this opened up some good torque gains down low and helped smooth the power curve up top.

The VVEL system is also extremely tune-able, and I was able to net extra torque down low with adjustments to this system — however through the rest of the curve Nissan got it mostly right, not surprising since the vehicle is stock.

Stock Tuned vs Full Exhaust Tuned

Not a whole lot to say about these results — clearly the exhaust modificationsexhaust_vs_stock_tuned_wm made power after we bolted them up to the car — but since our starting point was already a “tuned” calibration, very minor changes were necessary to extract peak gains from the parts and the fueling was still dead on since the stock intakes had been retained for this portion of the test. I expect this would not be the case if the car was still running a 100% factory tune on the ECU instead of my tuned calibration.

Full Exhaust Tuned vs Intakes & Full Exhaust Tuned

Depending on the intakes you chose to put on a vehicle tuned via MAF (aka AFM), you can skew the fueling dramatically — fortunately with the Stillen V3 long tube intakes I found that the mass air flow calibration was very close to the stock intakes and only required some minor adjustments to maintain proper fueling throughout the curve. However, even with perfect fueling, these intakes actually LOST power throughout the WHOLE power curve.

You might be thinking to yourself, “Whoa, what? They’re just filters on a stick….”. Indeed I was quite surprised as well.

That’s where the tuning begins — the engine required significant remappinstillen_vs_stock_with_exhaust_wmg of the VVEL system to not only return to the power the stock intakes were making, but also gain power over the stock intakes. After fully retuning the ECU, our results are some minor torque gains down low and through the mid range, and about 10-12hp on the top end.

My personal thoughts? Wow that was a lot of work for minor gains — but it does go to show how a naturally aspirated engine is a finely tuned machine with all the parts working “in harmony” with the ECU mapping to actually make power. Sometimes one small change can have drastic effects.

Some fun

Well, with that out of the way, what do the gains look like over the “stock tuned” setup overall?


And what does it look like over a completely stock vehicle?


Scion FR-S/BRZ Tomei Unequal Length Race Header

It’s always quite fun and interesting to progressively install new parts and retune a car to see what kind of relative change we see with those parts. This weekend I had the opportunity to help Jay retune his 2015 Scion FR-S after he installed his Tomei UEL race header. We had previously tuned this car when it was stock (well, stock being relative — he had a slightly modified stock airbox and the stock muffler delete, nothing major).

Jay FRS Stock TunedThe results with the car “stock” tuned looked like so. Very healthy pick up for just a tune.


Well on to the race header — after Jay installed it, we baselined the car on the existing tune to see just what the changes were from the part alone. It looked like stock_tuned_vs_header_untunedso.  I was a little surprised to see the results as we gained almost no power through most of the power curve with the part — it did however fill in the torque dip area, which was pleasant to see.

Next up is the retune. I exclusively used ECUTek for tuning these vehicles — they have the best stock ECU solution on the market with superb support. I knew there was definitely more in it — the motor on the car has dual VVT and quite a bit of work can be done to squeeze out any “hidden” power the neheader_untuned_vs_tunedw parts (the race header in this case) can support. Sure enough, we got solid gains! The graph on the right shows the gains from tuning  over the race header baseline, very pleased with the power pick up.

Let’s compare that to our stock tuned power curve — and you can see a very solid power gain all across the board over the previously “stock tuned” car. The
stocktuned_header_tunedmid range torque pick up was quite impressive — as much as 28 torque to the wheels with the header and retune. I have seen other headers on this platform pick up more power on the top end — but they did not fatten up the torque curve (especially in that mid range dip) as much as this header does. So it’s definitely a trade off if you’re looking at this header as your next mod.

Where does the car stand overall from when it was “stock”?





Tested: 2006 – 2011 Honda Civic Si Hybrid Racing Cold Air Intake

Years after the release of this intake I finally had the chance to do a true before and after impartial test of this intake. One of the biggest hyped intakes on this platform — and it really does work.

Now this is a TRUE test of this intake, not your “average test” where they slap on the intake and tune the car and everything that changed was “gains” from the intake. No… just no. All the big intakes require custom tuning or in many cases the car just won’t even run. To combat this inability to “baseline” the car after the intake was put on, many will skip an important step and just slap the intake on and tune the car — not a valid test in any sense.

The simple, yet more involved process:

  1. Baseline the car as it comes in.
  2. Completely tune the car (not this 4k rpm+ rip it and ship it trash for peak #’s).
  3. Install the intake.
  4. Completely tune the car with the intake.

We’re looking at more than just peak numbers, we want to see the whole curve to observe gains and loses throughout the power curve. Between step’s 2 and 4 we now have a valid comparison for the power the intake was responsible for.

So, today our victim was Randy. He purchased the Hybrid CAI from me and turns out his car was a completely stock 2011 Civic Si. Perfect!

I baselined the car completely stock, then plugged in the Hondata FlashPro and stock_vs_stocktuneddid a full tune on the stock car. The results are as follows. Dashed plot is completely stock, solid plot is after the vehicle was tuned. As you can see, pretty good gains across the board just from tuning a stock vehicle — if the vehicle isn’t tuned prior to parts testing, these gains would of been lumped in with the part, which is simply not accurate.

Max got the stock intake torn out and the Hybrid CAI installed. Istocktuned_vs_intaketuned went back in the car and on the laptop for more tuning. Here are the gains the Hybrid CAI facilitated (with more tuning of course) over our previously TUNED vehicle.  Aside from the small loss between 2500 and 3000 rpm, the Hybrid CAI is a stellar performer across the rest of the power curve, with gains as low as 1700 rpm.

So there we have it, unequivocal proof the Hybrid CAI makes power. What were the overall gains from tuning and the intake over a stock car?


Tested: Full Race Catless Downpipe for 2012+ Civic Si

A frequent question that gets asked is “What downpipe makes power on my 9th gen?” I have gotten in the habit of simply directing people to Full Race Motorsport’s website as we use their catless downpipe & exhaust on our supercharged vehicle, and I know the setup makes power.

Now here’s empirical evidence that it does.

Philippe was down at the shop and had us install the Full Race catless downpipe before I tuned his 2012 Civic Si. The vehicle came in with the following modifications on it already:

  • Invidia Q300 Exhaust
  • HPS Intake Hose
  • K&N Drop in Filter

Now from previous baselines of completely stock 2012 Si’s, I know they do about 160-164whp on our shop Dynapack. Before we installed the downpipe we baselined the car as it arrived. Sure enough, it did about 162whp with the power curve I’m used to seeing on a stock 2012 Si. This leads me to make the following conclusions:

  • The HPS intake hose and K&N drop in filter do absolutely nothing. Pretty pointless modifications and honestly a rip off (spend your money elsewhere).
  • The Invidia Q300 is a nice sounding exhaust, as always, but does not make any power, at least not without a tune. Maybe this will change with a tune?

We installed the catless downpipe, and put the car back on the Dynapack and randp_vs_nodp a couple more baseline pulls on the stock tune. The results are as follows — solid line is with the downpipe installed, dashed is before the downpipe.

We netted as much as +10whp and +10wtq from simply installing the downpipe. That’s a sizable gain for a simple modification.

tuned_dpNow let’s throw a good tune on the car… and the results are as follows. Solid line is fully tuned, dashed line is our baseline with the downpipe installed. The tune netted as much as +12wtq in spots and as much as +18whp on the top end.

dp_tuned_vs_nodpWhat’s this look like over the original baseline before the downpipe was installed? Here you go. Netting almost +30whp in spots with a downpipe and tune on the top end. Sizable gains, the part worked well and the tune brought it all together.

How does the exhaust factor into the power curve? Until I do a fair comparison of an exhaust swap on the car I can’t say with absolute certainty. However, we do know what other parts do make power already — A CAI nets 4-5whp, which would put this car around ~190whp, which is about 3-4hp shy of what the average 2012 Si maxes out with using bolt ons on this Dynapack dyno. So to make an educated deduction — an exhaust may net 3-4hp and maybe some mid range torque due to the ability to adjust the variable valve timing on the motor. It also seems that a 3″ exhaust would be the way to net any power at all, and anything smaller may not net any gains. With the integrated exhaust manifold design on the 9th gen cylinder head, the gains we’re used to seeing with a 3″ exhaust on previous K series engines don’t really hold true on the K24Z7.

Safe to say — if you want PROVEN performance, a good catless downpipe (Full Race works well as I’ve shown) and a good tune will get you 95% of what you’re going to get N/A with bolt ons. A cold air intake will net some power as well — and the exhaust is a wash at this point it seems.

Honda Tuning: What the hell did I just look at?

Introduction (bear with me!)

In an era where the Internet is “king” when it comes to information sharing, gathering and overall knowledge — it’s amazing how much misinformation (whether just misleading or straight up lies) there is to wade through in the “tuning business” — especially where it comes to the Honda market. Sometimes it’s even hard to discern what is fact and what is fiction — there are so many “big names” out there with fantastic accomplishments that arguably should be contributing to the fact pool. Unfortunately in a market that is cut-throat it seems many are content to just “do what we do” and keep pouring bucket fulls of garbage into the fiction pool. Whether it’s simply due to ignorance, catering to a target audience or just to make a quick buck — I do not know. I’m going to take some time and share some facts about “what the hell did I just look at?”.

Now before someone gets their feelings all hurt and goes on some tuner battle rampage — I’ll say this: I do not care about your feelings and you can’t hurt mine. You have no idea who I am and why I’m in this business (it’s not the quick buck — if I wanted to get rich I wouldn’t be tuning cars).  I am not naming names. Not only is that unethical, but it just plays into the same garbage bag of fiction this industry is flooded with.

Everyone who’s spent time talking with either myself personally or been to the local shop knows one simple truth about me — I am brutally honest and my whole goal and business ethic is to provide the best product with the best support in the industry. Your project is my project — if it’s something I personally wouldn’t be happy with driving day to day (for the street cars we work on) or taking down the track, then it’s not good enough and it needs to be looked at until both myself and my customer is happy before I sign off on it as “complete”. Another fact few may know — back when I first entered the Honda market I used to do the tunes for free. Why? Countless complaints from members on various online forums about their vehicles after they were “tuned”. In an effort to help the respective communities I offered a helping hand to share my experience and get people on the road and enjoying their rides. Obviously a business model of “free” never paid the bills nor compensated me for the time invested… So here we are today — and a midst an industry where many didn’t greet all our methods with open arms (to put it lightly) we’re still here and not going anywhere.

So what is the point I am getting to? I have always had an open door policy — not only free touch ups on any tunes we’ve done over the years (on vehicles where mods do not change) but also free datalog reviews for anyone concerned with how their vehicle is running, whether it be on a basemap or a 3rd party tune. I want to share some facts about what you want to look for to make sure you got not only the tune you deserve — but the tune you paid for (remember — you’re paying for the knowledge and experience of the tuner of your choice… you’ll be surprised what you get, even from the “big names”). There is so much that can be discussed — so I will just limit this post to Honda K series, as of this writing it is a widely popular platform.

 Wide Open Throttle

Rather than try to show you what you SHOULD see, which can vary a bit with the application the vehicle/build is targeting (yes, you tune a road race car different than a drag car which is also different than a street car…), I will show examples of what you should NOT see in the frame of a pump gas vehicle. Not only is the K series a VTEC motor, but it also has variable valve timing — VTC. Something many tuners seem to forget, or simply do not understand? I’m not going to touch upon ignition timing as that discussion is a very lengthy topic on it’s own.

The vehicles in the following example are powered by a K24Z7, but the same information applies to the K20A/Z and K24A variants as well.

During wide open throttle the vehicle should be running in “open loop”. What this essentially means is it’s running a fixed set of values and compensations (IAT/ECT and the like) to hit optimal targets — the ECU cannot and will not change these values based on certain sensor feedback (IE, changing the fueling based on the O2 sensor reading).

cam_example1The following graphic demonstrates a very poorly tuned WOT (wide open throttle) supercharged vehicle. The fueling (AF.Corr value) is extremely lean through a vast majority of the pull. The cam angles (VTC) look like they were touched — but not even remotely close to optimal on the setup. VTEC was also not properly set — ~4100 rpm on a CT-e supercharged internally stock K series is just silly. To top that off — the car was actually tuned on the dyno (I typically am a bit lenient in what I see on street tuned/eTuned vehicles I review unless the mapping was blatantly a mess). How this can even be remotely possible given the tools for the tune were in a controlled environment…? Simple: lack of experience of the hands working the tools… the tools themselves are not always to blame.

cam_example2Even worse… here’s the SAME problems on ANOTHER car with a CT-e kit. Same exact issues — but even worse, the cam angles are basically what a completely stock (unmodified) vehicle runs. VTEC is also at the factory point…. which is beyond silly on a car with a blower on it. Also tuned on the dyno. I’m just appalled.

cam_example3But wait — this isn’t just plaguing CT-e cars, the Kraftwerks cars are getting hit just as hard. Even worse this time — 16 AFR while in boost? That is beyond ridiculous — I’m surprised this motor didn’t melt a piston or two. VTEC wasn’t even remotely accurate and the VTC settings were a far cry from optimal. Also a car that came off the dyno, done by a shop that has some wicked fast cars (actually all 3 examples were).

I could go on — I have examples of turbo K series that are just as interesting. But it just gets more and more depressing, and that is not the goal of this thread. It seems that way too many tuners are simply not well versed in what is required to properly map a cam phasing/VTEC motor — and that is just unfortunate, as customers are shelling out money for what they believe is a good map.

cammapEven worse — we have your average copy and paste K series tuner. What does this mean? On your typical K series map, you have 5 or 6 cam angle “break points” for fueling and ignition for low cam (VTEC OFF) and 5 or 6 cam angle break points for high cam (VTEC ON). Proper fuel mapping of a speed density (“VE” — volumetric efficiency) calibration requires mapping each of these individually because as the cam moves, the fueling demands of the motor will change drastically based on the requested position of camfial1the cam. So what’s the copy and paste map? That’s when a fixed fuel map has been copy and pasted across every break point (example to the left is one of the above CT-e S/C tunes — I only show 0 and 30 as the car was not even mapped past that). You can see they are identical in the example. A properly tuned map camgoodwill look something like this example to the right. Notice how the are drastically different? Because the engines demands when the cam is at that point is that much different! Why is this important? I address that in THIS article. When I see a copy and paste map I ask myself: “What exactly was tuned?”. It’s a 20 minute map if I’ve ever seen one: rip it and ship it. There are a couple of exceptions to this — one example being if you run a very aggressive cam that can’t make it to say — 40 or 50 vtc without making piston contact, then you cannot map those break points (and should not try) and you don’t have to change them or you can just copy & paste your last tuneable break point to them (for example if the cam was safe to 40, you can paste the 40 break point to the 50 break point or just leave whatever is there as the ECU will never reference it).

I have heard such excuses as “well it’s a turbo car which will just blow boost out with more cam timing”, “I spent ALL DAY on the dyno, it’s fully optimized!” and “well the O2 sensor is just wrong or the fuel trims are screwing it up” (which can be a silly excuse when the car in the example also has an AEM wideband in addition to the stock one and they match exactly…).

Yeah…. no. I tune the exact same cars, with the exact same setups, and I have tuned a LOT more of them than any local shop has tuned. I can recognize a faulty O2 sensor 99% of the time just from the datalog (yes sometimes an occasional one will slip by — they can be sneaky). If you spent “ALL DAY” on the dyno and produced the ticking time bombs from the example above or turned on closed loop at WOT (by default all these cars will go “open loop” the moment the car is making boost) — rethink your career choice. It may be hard to sift through the fairy tales sometimes — but open your datalog and look for yourself.

Wait again — I have one more excuse, and this is my favorite: “it made power on the dyno, you saw it!”. Sure, it did. Even the worst tunes will make peak HP numbers that look good — especially when you throw forced induction at the motor (what’s a motor to do when you’re cramming air in there??). We can really be tunnel visioned by the peak numbers from a dyno chart — so much so that we miss the bigger picture: the full curve. The examples listed above are what I’ve classified as your classic “start the dyno pull at 4500 rpm and stop at rev limit”. Great for numbers, but not very useful in the grand scheme of properly mapping a K series vehicle. What about the whole curve? What about everything down low and mid? These are some things we should be thinking about when handing over our vehicles to be tuned. In every example above the car made better power across the board — not just better, but safer as well.

You might be going — hey Vit how do you know? Well… going back to… I work on the same cars and have been through many more of them than any shop you can name. I do not want to post examples of what properly mapped cam angles, etc, are, they will vary a bit from car to car, setup to setup — on top of which there are some places that love to pass off other people’s work as their own just because they added 1 degree of timing or changed the cam angle 5 degrees (I can always tell when a shop ripped my map off a customer’s car and use it as one of their “own” — my techniques are quite unique and I can spot my maps very quickly). The above are just some examples are of things you SHOULD NOT see on a properly tuned vehicle. Feel free to message me if you have questions and I’m more than happy to have a discussion and share some knowledge.

 Part Throttle

Among the ignition and cam angle mapping you also want to optimize closed loop fueling on the vehicle. I will not touch on the cam angle and ignition aspects as that would simply be way too much to write about, and there is a fair bit of leeway on how you can map VTC (cam angles). Ignition also isn’t nearly as sensitive at part throttle loads due to much lower cylinder pressures (although if timing is way too low it can and will affect drivability).

So assuming a clean ignition map, the most important aspect is to get fueling at light loads as optimal as possible to keep the closed loop feedback to a minimum. Why is this? Because the “tighter” the “trims” (short term and long term) that adjust the fueling to keep the car near stoichiometric during light acceleration and cruise, the smoother and better the car will drive (and make a bit better power). What closed loop does is essentially add or subtract a “trim” to get the fuel target back to stoich — ~14.7 AFR — under light loads. This also ensures good fuel economy. You can view these trims as “STRIM” and “LTRIM” or a similar name in most engine management systems. On most Hondata systems “LTRIM” is typically 0 as it has been disabled, and the ECU only uses the “short term” (STRIM) trim.

So what happens if these “trims” are way too great in one way or another (to far negative or too far positive)? You now start experience weird issues — bogging out, hesitation, misfires, car stalling out and the list goes on. Sometimes the car is essentially undrivable — even though it “made power”. Just because the car was “tuned” doesn’t mean the whole map was given full attention — I have seen this so many times that it’s basically the “norm” in the industry. Too many of the uninitiated in what a “good” driving car is swear by tunes which are far from good or smooth when in actuality they have no idea they are literally behind the wheel of a car that drives like complete crap. Yes, I said it, crap. This isn’t meant to hurt feelings, it’s a matter-of-fact statement. Sometimes we just don’t know what we’re missing.

So where’s a happy medium? Rule of thumb, acceptable is +/-10%. Where I like to see it? +/-5% if possible.

strim_exampleI will share two examples of what you don’t want to see. First one is actually an eTune done using speed density fueling I had the pleasure of reviewing for a fellow car enthusiast. One way to view the trims is to add them to a graph view, which is what I’ve done in this example — we’re at -25% and the car is STILL rich (13.8 afr) coming to idle. The complaints on this vehicle were of hesitation, bogging and the idle wanting to stall out. We can see why…

In the next example we have a newer Acura that is only tuneable via AFM (no speed density on this platform). You before_histocan put such a vehicle log into a histogram to review the fuel trims. It was painfully clear that the person mapping this vehicle had no idea what an AFM was or how it was properly calibrated. The ECU was sitting well into the -30% area (worse actually after the LTRIM was added in) with a “mean” (average) of about -22%. This is just horrible. In practice you should see something like now_histowhat you have in the following graph to the right. We are mostly +/-10% with a mean of +/-5%. Because of how AFM cars run and transition into open loop,  the ~3.5v to 4v area on this vehicle being around ~-12% is actually acceptable — granted not as ideal as I’d like it to be, but sometimes you have to make a small compromise — and in this case its only really 2% away from “acceptable”, and has  no impact on drivability compared to the prior mapping that was on this vehicle.

Dyno vs eTune

This is by far the silliest argument I have ever had to take part in. There are good dyno tuners. There are good eTuners. There are horrible dyno tuners. There are horrible eTuners. Easily summarized: there are great tuners and there are horrible tuners. Just because you chose one method or another does not guarantee you a “good” tune or a “bad” tune.

There are shops that vocally hate eTunes — good for them. They have a business model to protect — and most have no clue how a proper eTuning is even done! Unfortunately a vast majority of them will lie and coerce some customers into a dyno tune. To me that is just a horrible display of integrity.  I have never had to coerce a customer into an eTune or a dyno tune by hyping up one method or the other — and what some shops don’t realize (or forget) is I have been doing this over a decade, on dozens of dynos of all kinds and via street/eTune. I like both methods and believe there is a good harmony to be had with the two — ultimately the experience of the hands behind the computer doing the mapping is going to determine the final product, not the method.

Yet there is a rampant collective if no-name mom & pop shops that have effectively no real tuning experience — but since they own a dyno they are automatically professional tuners and because their dyno spits out numbers for such and such setup that automatically makes it a “good” tune and a “good tuner”. Newsflash: the dyno sheet does not dictate tuning ability nor does it determine how the vehicle performs (how “fast” it is). They are a tool, nothing more. That’s it. Ultimately the numbers you get from any dyno are absolutely meaningless without context. Guess what? Your typical roller dyno is cheap — $15k – $25k installed for a standard inertia type dyno. Any automotive shop can afford to lease one over the course of 5 years (standard lease). Too bad you can’t just buy personal tuning experience with a credit card…

The back and forth on this topic has however created some very amusing aspects. Namely one big one and I like to call it “jumping on the eTuning bandwagon”. Mail order tunes have always been around — it’s big in the Ford/Dodge flash device market and even on platforms like Mazda/BMW/Chevy. I have had the great pleasure of promoting the eTuning market to where it is today in the Honda/Acura word, and my popularity has been a great indicator of this. I have a passion for what I do and I’m not going anywhere — and I appreciate all the support my business has received over the years.

Due to my success, I’m seeing more and more so called “haters” now jumping on the band wagon. Everyone wants to be an eTuner now that we’ve proven there is not only a demand, but a NEED for it (not everyone has a good tuner nearby…). The level of hypocrisy (irony maybe too?) is just astounding. The unfortunate aspect here is — producing a good eTune is actually harder than a dyno tune. There is more work and more thought involved in the how and why of what you are doing. Bluntly put — we have “tuners” that are releasing under par work from the cars they put on the dyno now trying to eTune the said cars. How can one expect a good eTune from shops that are releasing tunes like in the previous examples? Bluntly — you can’t.

Anyone claiming an eTune is “easy” has never done an eTune properly — sending out a generic basemap and just fixing some fueling is by far NOT a full and proper map. Others will send a map from a previous car they’ve street/eTuned or dyno tuned and again — just fix the fueling for you. Hell some even advertise as much. There’s nothing custom about it and very little actual tuning is involved. It’s down right shameful is what it is and the results are far from amazing.

It’s definitely easy though — easy money too, right? Easy to catch a new comer into the “tuning scene” and take advantage to make a few bucks. And then easy to write it off to “oh well you only paid for an etune,  you need to go on a dyno”. Yeah right. This isn’t what my reputation is founded on and we’ll never go that route — every map is tuned from the ground up, a truly custom experience. Every car is different (yes even with the same mods) — and should get the attention it deserves (and that you’re paying for).

But hey, with a market where your entry only requires you to own a laptop and download some free software — anyone can be a eTuner! Or at least play like one — and unfortunately I do have to say that the vast majority of sites popping up offering eTuning services are nothing but crap and are run by complete hacks. It actually pains me to say that as I support eTuning and it can be done quite well in the right hands (I’m very successful with it — spawning some of the fastest K series vehicles in the 8th and 9th gen markets!).

On the flip side — the vast majority of dyno owners have no idea what they’re doing with an ECU beyond the graph that is printed out on their dyno computer. I guess that makes for a happy medium?

Really though? It just sucks for the consumer.

Final Thoughts

Some people may now go — wow Vit you’re a complete asshole. I’m sorry you feel that way — maybe one day you’ll get a chance to meet me and form a real opinion. I certainly am not motivated to be an asshole — what drives me to succeed and pushes me to try and be the best at what I do is my passion for my work and my desire to never see a fellow car enthusiast with a vehicle that’s been butchered. I’d rather be an asshole and have someone with a car they enjoy with the support they deserve than to be your best friend and leave you with a car you don’t want to drive. But hey if I make a friend while taking care of a customer — even better. I’ve build some great relationships between many customers and vendors — and I hope to keep that ball rolling.

Hopefully I gave us all something to think about — and some insight into what to look out for so we’re not caught asking ourselves: “What the hell did I just look at?” The haters can continue to hate all they like — I’ve found the more they hate, the more it indicates that I’m doing something right. I don’t know who they all are — but apparently they know me. Speaks volumes I think? While they spew senseless ramblings on whatever Facebook section is popular that day about “what they heard” and “just saying” with the vocabulary of a 3rd grader I will continue taking care of my customers, improving rides worldwide, going faster and bringing new products to market.

In closing — they may try to duplicate, but they can never replicate. If you want the best your money can buy — you know where to reach me!
