If so, what springs are you running in the wastegates? That is what boost you should be seeing, atleast in the honda turbo world its that way. Correct me if im wrong.
A boost controller (or an ECU with boost control) will override the wastegate spring by bleeding off the wastegate reference pressure. So the wastegate spring doesn't really set much of anything unless you're running the wastegate by itself with no other outside interference.
But yeah, you're right if there isn't a boost controller.
