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!
