I currently run with the actuator unplugged. I was was deceling today and i heard kind of a very rough air rushing sound. Almost a grind... i was wondering if it the gate somehow opened. I never heard the sound before

Probably just back flow.
:whs:

How hard were you getting on it when it happened?

If you are running WOT and suddenly let off, all of that pressurized air will bleed back through the compressor and cause the compressor wheel to hit the housing which could have been the "grinding" noise.

Hows the condition of your compressor wheel and shaft play?

i dont remember being too hard on it. I let off hard all the time and hear the surge, but this had to have been more of a grind... Last I check the wheel is fine. But I will dig it further. thanks
