Anyone ever have issues with boost creep? My old setup (stock 2.5 with a garett, intercooler, and 3" exhaust) would boost creep up to about 18 psi even with the wastegate flapper unhooked. My new setup is a 2.5 with a BMF intake, log manifold, hybrid Turbo, and a big valve head. I can control boost to 5 psi until 4500 rpm then it starts climbing. At 6500 rpm I am at 20 psi.
I don't see many people running external wastegates on their 8v engines so why doesn't mine hold boost well?
