GReddy Type-S sputters under boost?
I have the greddy type-s single spring mod and the top screw turn about 2.5-.275 turns. Everything seems fine, except sometimes under boost it spudders, almost as if its opening and closing really fast. Doesnt seem to happen under low boost, just when Im building to higher boost. Any ideas? And yes im recirculating.

it probably means your spring in the valve is too stiff, try loosening that screw or something...i have a forge bov VTA and it was doing the same thing, its technically called compressor surge, or flutter but its annoying. try it out
