This question may sound a little vague, but I was wondering if you still need a wastegate at high boost psi. I'm thinking around 30 to 40 psi. Obvously, I am going the have the engine reworked, and may decide not to go that high, but if I do, I can't seem to find any wastegates rated for over ~22 psi. Does this mean that one isn't needed when your setup uses this amount of boost. Thanks in advance.
