you wont get boost creep with the .86 AR (stage 2). originally I had .64 AR (stage 1) with internal wastegates and I had trouble running less than 13psi, I got custom 2" restrictor plates made up to put in my exhaust at the time and it worked great, basically adding back pressure prevented exhaust gasses from bypassing the small wastegate opening. I was able to run 10psi on that setup. Now i'm trying to dial in 17psi
