Hi all
I have just got my car back from getting new clutch full service air intake and new custom downpipe as well as a few other little bits, the car is going damn well and running well but when I sent the car into the shop it was boosting 16psi (with a full exhaust) and now I have got it back its only boosting 10
Anybody heard of this before is this an easy fix ??
All help is appreciated
Cheers
