ok this was probably already covered but i couldnt find the thread. i have a manual boost controller, an intake, and a full 3 inch exhaust. i have my boost controller all the way open and i read about 8 to 9 pounds of boost but i shimmed me wastegate even though its not recommended and im still reading the same boost on my gauge, why is that?
