F.A.S.T intake whistle

    I recently installed a 102mm FAST intake along with a BBK 102mm throttle body. The intake installation instructions suck and were for an LS7 [FAST says those are the right instructions]. Regardless, I got it installed, but there is a whistle that is at best annoying. I can't seem to isolate where it's coming from. Anyone come across this before?

    @FANTA-Z , I know you have worked on these before so hoping you can help this guy out. Of course anyone else that sees this thread can help out, I just don't have enough experience with these engines to begin to guess what is causing the sound.

    Read somewhere it might be the IAC opening making the whistle, and smoothing open/exit will solve it.
