:I bought a 1990 twin turbo yesterday in sc and drove it all the way back to my home in va. Turbos would spool perfect but the car was getting no boost from a busted intercooler. I had a set left over from my last 300 so I put that one on. Now I can actually build pressure with my boost leak tester and it will just leak out very slowly from somewhere around the turbos...(before it would hold no air). I was about to take the car down the road and now I have no boost and the gauge is pegged in the vacuum. The wastegate actuators are not moving at all when I rev the car, which doesn't want to rev above about 3 grand. Someone please help... Thanks, Paul
Also, I just ran an ecu self diagnostic test and its not showing any codes. 55
