Ever since I swapped to a pt76/75 over my mp76 I cannot lower my boost enough. I logged 16psi this morning and I need to lower it to a steady 13-14. Am I simply over flowing my wastegates capabilities? Need this fixed as local truck shootout is next week!

Lol it's because now you have a turbo with some beans. 16psi has been my dd low boost for over a yr now Bet you have a shitload more power now.

Gonna have to redo you wg routing. Air flow in the crossover doesnt need to make any hard turns to get to the face of the wg valve. Kb sets his up for a 90* turn which doesn't work well for good turbos and low boost. Needs to kind of look like a Y pipe split.

Try a lighter spring. Or take the spring out and try again.
This will let you know if its a spring or the gates size or gates routing.
