Here is a look at the 50-100 for my 08 STI. Full build details:

This is now running E85 on the pump tune with injector scaling changed. I'll do an E85 tune here in the next week and see if I can get a bit more out of it.

Vehicle: 2008 STI
Motor: Built WJ257
Turbo: EFR7670
Boost: 24-25.0 psi
Transmission: Stock 6-Speed
Redline: 7800

Cobb AP SD
Weight: 3450 lbs empty, with me 3648lbs
50-100MPH: 3.99 (24-25psi, 480ish whp), 4.99 (21-22psi 430ish whp)

You can see that the higher boost makes a bigger difference at the lower RPMs in 3rd gear. The slope once in 4th is almost the same.

I also did a run in 4th gear only, and indeed it is slower. The 60-130 might be different, and I'll be curious to give that a try.

Also, here is a look at boost for the faster run:

I really should turn on flat foot shifting.. that boost drop sucks.
