Bad Waste gate I have a STS Turbo car... I went threw the car from top to bottom fixed 3 Boost leaks i have found. there is no more boost leaks i pressurized the system and it holds now. Anyways when i drive the car i wont make more then 5psi of boost and i bypassed the boost controller and still no diff.

where is it referenced? what spring is in it? you can check it by getting an air fitting and installing it in the bottom port and use air pressure and a guage to see where it starts opening and at what PSI. if it was bad then it probably wouldnt open and it would cause boost spikes and would pop your motor.

it is ref off the intake. but it could also be stock open and cause it not to build boost. Its is a Gt67 turbo. the turbo alsohas a good amount of shaft play wich i really dont like
