Jack, I just replaced my mufflers with muffler delete pipes and my boost dropped down to only about 13 psi. I tightened the waste gate rod to where I can barely reattach it and still only have about 14 psi. I removed the vacuum line from the waste gate actuator and it only came up to about 15 psi. I have checked my turbo, waste gate puck, manifolds, and the weld you did on the drivers side manifold and I can't find any exhaust leaking by before or at the turbo. Am I missing something? Is it possible that the waste gate actuator was failing and this aggravated it (or coincidental)?
Thanks in advance, Curt.
