Now i know that a BOV is used to relief presure in the intract track when the throttle body plate is closed suddenly........but is that the BOV tha causes that really Awesome sound after a GOOD burnout...... u know what i'm talking bout.....that multiple flutter of air. An y does it make that noise

P.S. its not just a real quick noise like from a shift.

Its the sound the intake makes after getting off the gas while the turbos are hella spooled. Right afterwards the big intakes tend to make that noise. mine does and I'm running BPU stock Turbos. The key is the stock BOV has to be capped off.
