whistling from greddy rs bov

when i am going at full boost i hear a whistling from the bov. it sounds like a line is crimped or cut somwhere but ive repetedly uninstalled and reinstalled the bov numerous times, and yet every time i boost it still does it. it blows off like its supposed to, but while boosting, i get a weird whistling sound. any idea on what this could be??

Boost leak, check the gasket and all your vacuum lines.

It's more than likely an adjustment issue. Try tightening it a few turns (maybe more) and see what that does. If you get surging, back it off a turn or so until it stops.

My car is well, it's like 10 lbs of shit in a 5 lb bag...
