I'm trying to fine tune my bov I'm afraid of getting compressor surge. I have a cheap ebay turboxs knock off. It has a weak spring in it so it has 6 washers in it...If i take all washers out the car will die after i let off the gas after full throttle. But I'm afraid if I have to many in it I will get compressor surge. As it is right now with 6 washers in it it holds all 15 psi I have, when im at a low rpm like 1500rpm's at wot and i let off the gas it will still flutter at that low of an rpm. Can someone guide me through this?
