hey guys im a auto mechanic, never messed with srt4s to much but know a lot about forced induction, ive checked for boost leaks and have 0 boost leaks, the only problem I found was a ripped intake pipe. when you drive the car it will not even build a single psi of boost, is the wastegate a common problem failing on stock turbos? the 2 things that im leaning towards is a failed wastegate actuator sticking open or a failed turbo. vacuum is between 18-20" at idle and no vac leaks around intake manifold, used smoke machine and soapy water. any help could be appreciated. also is there a way to test wastegate actuator with everything on the car, trying to pinpoint problem without tearing stuff out to keep cost down for my customer
in case you haven't figured it out yet, this place is dead...if you still need help, you'll probably have better luck checking srtforums.
