Default 2008 subaru sti results

Hey guys just posting what my 2008 subaru sti made on the dyno it has a full 3" turbo back exhaust AEM cold air intake 850cc injectors 255 walbro fuel pump. On e85 it pushed out 371 whp and 399 whtq. On pump it made 321 whp and 371 whtq. Do these resluts sound right for what is done to the car? Another forum website said it was way to high.

Edit I'm an idiot and didn't realize this was an 08. Looks realistic trap speeds would say 100% though!

Ya numbers are just numbers. Those are really high numbers for a basic stage 2, so you can't compare other cars side by side. Some tuners can get different power bands than others, but realistically a stage 2 STi will be the same as any other stage 2 STi.

What does a stock car do on that dyno? As long as its safe and your happy thats all that matters. Sounds high compaired to most dynos even on e85.

Numbers vary from dyno to dyno too. Im taking my car in for a tune this Wednesday. Just a protune with the AP because i have 5+ years of extended warranty to think about...ill post the results for comparison between stock and then the tune. I did this for my wrx with a drop in filter and the increase from stock power was +25 wtq and whp. The power delivery and feel of the car was drastically improved...

Would be nice if I was making that kind of power I guess when I go to the track and run my car ill see how I compare with all the other cars ha but thanks for the advice guys and you know if you tune on the ap your warranty does get voided because they check the ecu and if they see the ecu has been modified they void the warranty happened to my buddies Sti and I work at subaru and I've seen it happen!

93 octane? I believe it. Those numbers sound reasonable. There's a 2012 a few threads down making ~40tq less than u on 91oct.

Slightly high but not impossible. MPH at the track will confirm though

Nothing crazy about those numbers. On pump (dynojet) I see anywhere from 300-330 whp for stg 2. I wonder what boost level this what at. Judging by the torque on pump, I'm going to guess 21-22 and the same boost for e85 hence the small torque margin between the two.

This topic has been debated back and forth. Recently it was explained thoroughly to me by a member on here...

I am an electrical engineer for a living, designing a PCB with IC's, a few ground layers, few voltage layers and some NVRam for storing flashable data is NOT hard.

That gentlemen, is what our Subaru ECU is, or a collection thereof.
Knowing how these components work, what "flashing" really means (in actual electrical terms) and understanding the bootstrap / NVRam flash area like the back of your hand (as the Cobb engineers have) means that you can answer this question accurately.

Therefore I am hereby answering this question accurately:
The dealer can tell you "unplugged your battery" if you flash your ECU, then return it to stock (AP Uninstall) before visiting the dealer for a warranty claim, or any other reason.

There has been talk of a CRCVerify run against the data. This is very feasible, most Subaru employee's don't even know what I just said, muchless what it means, muchless how to do it. On top of that, the CRC's would MATCH the factory .BIN they are comparing against. Hell they could even generate a SHA256 checksum against it it doesn't matter when you uninstall an AP the EXACT SAME 0's AND 1's are flashed back to the NVRAM flashable area that were there before, with the only exception being the temp tables (AF Correction learned, etc) which are populated as you drive.

Guys seriously can we please stop debating this, it's annoying as ****.
Don't mean to thread jack but also please note that your flashed ecu doesn't "void" your warranty. It can just cause your warranty claim to be denied if they can prove your modifications (be it tune or mechanical) or driving style (mad clutch dumps bro) are what caused the failure. This is good information because I too thought you were ****ed even if you were just stage one. Take it for what you will.

Nice numbers OP hope you enjoy the new tune ! Feel free to e mail the plot to me at [email protected] and ill host the pic for ya.
