If I set the setting kind of high my car makes a noise. The noise sound like the bov is releasing air psss pssss psss with out even letting go of the gas, and it only happens when I go around 5k rpms. I have a HKS ssqv bov.


Is this normal? can some one let me know please help.

 

You can try the adjustment screw on the bov or you may have a boost leak. hard to tell without seeing/hearing it first hand. good luck.
