    Just finished up the pumpgas tune on this 2007 sti. Car made amazing power for a subaru on 93oct. Even more impressive is the powerband of the car making peak power at 7500rpms just shy of the revlimit.


    Billet crank
    Manley rods
    CP pistons
    Cosworth oil pump
    Cosworth bearings
    Kelford Cams
    Cosworth Intake
    APS Twin Scroll rotated turbo
    850cc injectors
    APS 3.5" exhaust
    Ecuteck (TSM Tuned)
    Race ported head
    1mm oversized valves
    Custom beehive springs
    1mm oversized valves

    Dyno run was at 24psi peak. I had to stop there because the injectors were at 96% at 7700rpms and the clutch actually started slipping.

    Pretty nice power there....esp on 93 octane. I'm impressed with it being an APS turbo....they tend to disappoint.
