yeah the externals have a bigger path for the exhaust gasses to flow. what exhaust do you have? I would advise anyone going with stage 1 turbos to only get the external wastegates for better low boost control.
I'm looking to have a machine shop fabricate some exhaust restrictors instead of going with HFC, hopefully that will keep me under 9psi with the controller off.
