you will hear the surge sound when the bov set too tight and during throttle release. the throttle body shut immediately and the pressurize air is trapped and travel back and forth throttle body and turbo compressor. the psshh psshh psshh sound is the pressurized air moving in between. really cool but not recommended if the boost is high.
bov sound usually will discharge once not psshh psshh psshhh. AFAIK FYI :D
