I'm new here and I bought a 2011 WRX STI new, now i'm on the boards simply because I'm now into modifying it.
A buddy of mine has a "Tial Stage 3 S4", its a 2002.
He claims that his car is faster than mine! I never was in the car when he put the pedal down, but i don't think its slow...
Do i have any chance beating him? My car is certainly newer and has 100k less miles than him, if that means anything lol!
edit: he has a Tial 650 turbo at 28psi
how much PSI does our turbo have stock?
