Message past my target setup. Thought the Greddy was the problem. Unhooked the vac lines to be safe and thought that I would only boost the wastegate setting(7psi). Shocked to find that I was still boosting 15-17psi under wide open throttle. I'm thinking the internal wastegates on my stockers are "frozen shut/rusted". I would test this theory out, if I could access the wastegate actuators. But, I can't find a way to get in there without removing a lot of stuff. I stay out of max boost until I can figure this out.
