Well i have noticed that anything over 10 lbs of boost it seems to be a sqeeling such as a boost leak or open vacuum line. It gets louder as i gain boost. Dont seem to be affecting it real bad or anything. Anyone have any ideas for that?

Does anyone have a diagram of how the EGR system should be connected? I need to verify I have the vacuum tubes hooked up correctly. If you simply switch the vacuum tubes on the butterfly valve solenoid, then it will stay closed while driving as it doesnt bleed off the pressure when the solenoid is shut.
