Well, I did a boost leak check, holds 22psi just fine, no leaks. Switched MBC's and I still can only boost 16psi. I did a vac test on the top nipple of the wastegate, it holds pressure without leaking ( not sure if that is even a test that means anything, vac tester was already testing my finger so why not
), BoV holds vac fine as well ( Synapse ). Might end up throwing the GReddy on next to see if its the BoV but I doubt that as I had no problems boosting last Friday until the vac line to the BoV popped off under the manifold.
Give me some ideas of what else to check, running out of them myself.
