Well, that all depends. It is basically more reliable and more efficient at holding boost then the stock one. The stock bov can barely hold stock boost levels, any tune and you need to upgrade. If you current bov doesn't gold boost like it should then you will notice a performance increase, vent to air bov's keep the unused boost in the charge tube from slamming into the closed throttle body valve and coming back and hitting the compressor wheel and causing compressor surge. This is mostly for the sound though.
