Today I put in new uppipe gaskets. The leak seems to be gone, but the severe powere surges are still present. If I load the turbo, let's say 55 mph in 4th gear and floor it, the boost bounces between 9 and 14 psi.???? Also, after the new gasket install, I get about 4 miles down the road and I get a CEL.???? Don't know what that's from either since I have a Godspeed downpipe and uppipe and never had a CEL before. I used a lot of bolt lube. Think that could have leaked into a sensor? Any suggestions on any of my problems? I'm about to go insane.
