For someone that's running ~10 psi with a 5 psi wastegate spring, the wastegates are going to be open a lot even at part throttle. I recirculated mine with a 3" catted FI exhaust, and I couldn't be happier. Sometimes I want more noise, but that's ok. I prefer wanting a little more noise sometimes over wanting less noise all the time.
