Matt's 08 STI - 300whp+ on 91 Octane!

Posted by Ed Susman on

Here's a nicely put together Stage 2 Plus setup that made over 300whp on 91 Octane!

This 08 STI has the following parts:

Basic built shortblock
Turboback Exhaust
Tomei Equal Length Header
Cobb SF Intake
Cobb FPR Kit
IAG AOS
IAG TGV Deletes
DW65c Fuel Pump
Perrin Turbo Inlet
Cobb AP V3 with EQT Custom Tune

Since this car has a built shortblock, the customer requested a somewhat more aggressive tune. We tuned the car at 19psi peak tapering to 14.5psi by redline. Its rare that a stock turbo Subaru breaks 300whp on pump gas here, but this one did so easily and consistently.
