7lbs is the stock wastegate pressure. You may have a bad boost solenoid if you're only hitting 7psi. The boost solenoid should keep any pressure from hitting the wastegate actuator until desired psi is achieved, then the boost solenoid will let air hit the wastegate to control boost. Got a manual boost controller to test with? I've got a stock actuator I can sell you but you should make sure yours is bad before spending money on a new one.
