As some of you may recall I have been having problems with a used factory turbo I scored and put on my truck a while back. Here's that thread-

Problems persist. My boost has been steadily getting harder to ring out. New fuel filter and air filter's clean. I did notice that there's STILL an exhaust leak at the ball -socket BS joint between the y-pipe and the up-pipe so I pulled it all off and swapped the y-pipe for another that is a VERY tight fit into the up-pipe, which is brand new. The fit is now so tight that I don't ever want to have to attempt to pull those 2 pipes apart. I took the exhaust housing off while the turbo was out and everything looks good and it spins freely. The wastegate is maxed out and the valve sits completely closed. I slowly put the whole system back on the truck ensuring that it all fits together right then fully tightened everything up. I even RTV'ed the intake hat at the intake manifold and the compressor housing. Took it for a spin- boost is even lower now. It is very difficult to hit 3 psi where it was easy to hit that before, when I was maxing out at 5. I see nothing awry, there no audible exhaust leaks and there's plenty of black smoke. The pyro is reading about the same as ever. I question my boost gauge but I also don't FEEL the boost so I doubt its wrong. I am at my wit's end with this damn turbo and getting sick of the truck as a result.
I am gonna walk away from it until late next week but I'd like to get some better results before I leave for Oregon in the damn thing in 3 weeks.
