Turning up Boost
I searched hopefully didn't miss it but how does one turn up boost on procharger? And does it require immediate tune? I'm at 5psi except 5 and 6th gear which only seems to get 3psi.

what size pulley do you have on it?... do you have a 4" inlet or a restrictor plate in the inlet?... did you get the tune/fuel issue sorted out?... I wouldn't suggest adding more boost until the car is running right... you will definitely need a retune to account for the added incoming air but you can safely drive around on the current tune until you're able to get the retune done... if you're tuned for 5psi just make sure you don't go over 5psi and you will be ok
