How much boost pressure can a built VQ37VHR withstand?

Jwick. That is my dyno. Actually one where I was running off spring pressure only. You can see this by the way my boost drops off really bad up top. The WG springs get hot and loosen up. This is why nobody should ever run off springs alone. After I figured out my MBC it held boost evenly across the range.
