got a blitz dd bov in my stock gsr doing 5psi. are you suppose to hear the bov when rev? you can hear it loud and clear during boost after 4k rpm. i have people say that it's suppose to be louder than type s even at rev. i have the spring tension adjust about half way, would it be better to have more or less spring tension at 5 psi??

 

looser tension=louder+ flutter
tighter=quieter and better sounding on the dd, with my expierence running it on my car.

Most people cant build boost by revving....too small a motor, too big a turbo in most cases.
