Whistling problem HELP!
I've been helping a friend on his 93 GT and we just ported his heads and installed a Trick Flow intake, BBK 65mm tb, BBK 65mm EGR spacer, CL 73mm MAF. And he has this whistle at low RPM's. I think I read something about the BBK thottle body have this problem. But I'm not sure. Any ideas about what it is? Or how to fix it? Thanks!

yes it is the tb..when they drilled the hole in the middle they didnt drill it at the anglle that the air would be going threw it at an idle..they drilled it straight..drillling the hole out at an angle is the propper way to fix it but drilling a sligtly bigger hole and turning down the idle screw afterwards will correct the problem also
