My Version VI has only 155awkw yet I managed a ~ 12.6 @ 109mph (from memory only went once because was scared of banging the 5 speed)
Only mods are 3"
TBE, Autronic
ECU, fuel pump, waterspray kit and tune.
I honestly recon its the cleanest example of a V6 STi in Aus. There is not a single mark on the paint of the car.
Love the version 6s.
