Just got in my Cobb SF intake with SF intake box, Invidia catted divorced wastegate downpipe, and an Invidia Q300 catback exhaust for my 2008 WRX. I have the Cobb AccessPort V3 as well. Is this all i need for the Stage 2+SF tune??? Also, im getting a whole new engine put in right now. The other one broke last friday running the Cobb stage 2 regular tune with a Cosworth High Flow intake i had one it. If course never had it pro tuned for that intake sooo my guess is it ruined it. Idk. I drag raced 6 passes in a row with this guy around town. But anyways. Im hoping this is all i need for the stage 2 tune.
