Well outside of a blown HG, recently. I was having difficulty building pass just under 10 psi for sometime now. If the boost controller was set at its highest setting and the vacuum line off the WG, it did not matter. It would only build boost up to a hair before 10 psi. After removing my exh manifold while changing my HG I could see the hot side of the turbo has a very large internal crack. Obviously, this is where my boost was leaking to.
