The wastegates on turbos are being pushed open by the exhaust pressure. I cannot get the stock wastegates to stay closed above 14psi... I unhooked boost line going to wastegates on dyno and wastegates open on there own.
Unsure if the engine being built an ported if making to much backpressure. Hoping z1 wastegates hold pressure.
