Sorry to post this here but its for a buddy of mine. I def didn't want to join a dodge site for this. I was hoping that someone can post any ruleouts on a boost issue. He has a 93 dodge. His loss in boost happens in 4th gear when towing and 5th gear when not. His boost gauge flickers between 15-20lbs. He has replaced mostly everything "pre-turbo" including the turbo itself. I don't know the make of the new one but it now has a wastegate as the old one did not. He bypassed his intercooler and intake box, and reinstalled all his stock parts. Any list of things that he can try will be greatly appreciated.
