i just put on my hks SSQV blow off valve and i started the car and reved the engine to about 4 grand and its not cherping its only lettin out air what can i do to fix the problem. and one other thing i just baught the radio harness and i plugged in the one that goes directly into where the old one was but where do i put the one that is for the speakers?? if it does in the amp where is the amp??

 

it will sound different under a load. Revving up in nuetral wont really make it blow off...especially at low/stock boost levels. Drive it around and check it out. A vacuum reduction will also make it blow off louder and even help the turbos spool up a little faster. Fail smog though. (CA smog at least)
