to get the BOV sound with a turbo car....(YOU KNOW vrrrooom pssshhh...lol) i was told that you would need to run a certain PSI (I believe it was 8 PSI) to get it everytime you switch gears....you still get that sound at lower PSIs but only at certain RPMs and not as loud as it would be at 8psi....im not really sure about these turbo cars...so can someone answer this question for me *BTW didnt know where this went* or do you always get constantly but the high the psi just the louder it is so you can hear it *sorry guys dumb question....i have basic mechanical skills*
