2007 STI - 311whp/330wtq

John@Precision · 03-05-2008, 09:14 PM

Dyno: DynoJET
Tuner: John @ Precision Tuning
Wheel HP: 311Wheel TQ: 330

Car Info
Year: 2007
Engine Management: Cobb AP2-93 Octane
Turbo: STock
Intercooler: Stock
Injectors: Stock -
Intake/Inlet: Aps 65mm CAI
Headers: Stock
Uppipe: Stock
Downpipe: Helix Catted
CBE: Invidia(I think)
Other Power Mods:
Walbro 255lph fuel pump

This car is running 18 psi peak tapering to 15psi at redline. The car has the stock injectors running 96-97% towards redline with the Walbro, so I chose to leave the boost and leave the timimng curve alone until he choses to upgrade. The car is only seeing 22degrees toward redline....so there is def more to go. This car is very strong and a pleasure to drive.

The more I tune the APS CAI(65 and 70mm) the more I like them. They have a consistent flow pattern, very little MAF turbulence. I am sure people will question my choice of AFR curve, but as I always say...every car is different, and this car liked the leaner spool and slightly leaner tail....so that is what I stuck with. I tried several variants, and this combo was best.

Thanks for looking.

Stage 2 cars- I like the stock airbox. If you want to go CAI-go APS, short RAM-Apexi.
