Since I bought the car I havnt been able to get past 8 PSI. I data logged and it stops at 8.25. I just replaced the Duty / boost solenoid which I thought the problem was but no diff. Now I even unplugged the solenoid completely and it STILL wouldnt go past 8 psi. When I accel moderatly I can hear a loud shhhhhhh coming from the turbo area which is the same sound as when I let off the throttle so im positive its the wastegate. Only mods that I know of are Downpipe, exhaust and Cobb intake. (I put in cobb intake recently so no prob there) How do you adjust the wastegate? Any pictures and info is much appreciated
