MK7 GTI IS38 Dyno comparison, Stage 2 vs IS38 with APR software

In this one we compare a MK7 GTI with APR Stage 2 software and supporting mods vs an IS38 Turbo upgrade. As always we did our best to keep each run consistent to the next. Runs were done a day apart, and the only thing changed was the IS38 and upgraded APR software.
***PLEASE NOTE THIS IS ON 91OCT AND CORRECTION FACTOR ON DYNO IS SET TO SAE
Once again we seen greater gains than what APR claims on their website.

Awesome video and comparison. It’s so frustrating to watch dyno videos and 99% of the time they will flash the chart up on the screen for about a half a second and it’s extremely blurry and out of focus or so far away it’s illegible. The whole reason for watching dyno videos is to see the chart clearly and understand exactly what it represents. Thank you and very nice work.

I fuckin love these dyno vids, you do a great job man. I also totally love APR even tho they get a lot of hate lately for some reason? I'm mk6 k04 APR high tq so a little different, but I've driven several manufacturers' tunes on a similar setup, and APR's drivability is straight up smoother than stock most of the time.. even if they're a touch down on raw power from other tuners. I was on REVO for Stg 2 and it would just torque spike and blow the wheels off for ANY reason haha, which was kinda fun if I wanted to hop the front end like a pogo stick. But APR does a great job of managing boost in 1st and 2 so it ends up feeling faster cause it just hooks up. There's a lot of value in that.

[@COMotorsports]

Feels faster and generally is. There's a reason they're as big as they are. And when you're that big you're bound to have haters. Thanks for the comments.

If you check APRs website you will see they focus on overall acceleration, including 0-60. They're not just focused on HP figures but are doing what they can to get as much power to the ground as possible on street tires.

This was dynoed in 4th which tends to be lower. In 5th it would have shown more power for sure. With all that said we typically see 330-350whp on stage 2 Rs on our 91oct.

[@hu5kyy280]

That’s so strange, Stage 2 making less power than Stage 1? Idk if it’s your dyno, but that doesn’t seem right

[@COMotorsports]

Stage 2 GTI... not R, there is a difference you know. It dyno's pretty much exactly as it should, on 91oct, even with the little PSA at the end of the video.

[@judahs3017]

Where are you guys located?

[@COMotorsports]

East coast Canada

So is it recommended to go full stage 2 first before upgrading the turbo, or is stage 2 not necessary?

[@COMotorsports]

Well, to do the turbo upgrade correctly you should have an upgraded downpipe and intake as well. Since those mods are required for stage 2 it only makes sense if you're stage 1 to do the upgrade to stage 2 while you save your pennies for the turbo upgrade.

CO Motorsports copy that. I’m going stage 2 and APR down pipe later this month since I already have the stage 1 and intake. Before he year is over I for sure want the turbo afterwards. Thanks!

[@COMotorsports]

@ no problem, good luck with your project.

[@COMotorsports]

@Bryce Czirr thanks man, we've only been an APR dealer for 13 years. For their software it was required, no false info here.

[@COMotorsports]

@Bryce Czirr unfortunately you're still wrong. If you look at APRs website a little further your will see that stage 2 is no longer available. That's because they no longer sell downpipes, which is the prerequisite for thier stage 2 files up until about a month ago. Now it's just not available for these vehicles. So yes stage 2 on these required a downpipe upgrade, no questions.

It has to do with our fuel, and the correction factor used for these runs. Typically 7rs dyno between 320-350 on our dyno with our 91oct fuel. The higher ones all have upgraded intercoolers.

We don't need to justify anything, fuel is what limits us on power, not the software. Whether we put APR or any of the other providers on the dyno there's only so much power to be had safely with 91oct on a stock IS38, simple as that.

I have dynoed a handful of 7R's on this dyno in FWD with near identical results. We give all results in SAE corrected to keep the dyno numbers comparable.
