How are you 'turning the boost up'?

A remap would be the best route, but with a MY98 STI you're facing the same problems as myself - the ECU! you'll need an aftermarket one.

However, Scoobyclinic are supposed to be able to remap this ECU (well a UK ECU at least). Give them a call to find out.

 

im gonna fit a e-boost controller, turn it up by say 3 psi then i was gonna just get it sey up on the rolling road?
