Default FAST LSX R 102 intake whistle....anyone else?

I just installed a FAST LSX R 102 intake on my ls3 with my stock throttle body, at idle no whistle, under a slight load such as going up a hill it whistles, called fast and they recommended putting sealant between the upper and lower sections, so i did, but no change. I can find no vacuum leaks, anyone else experienced this?
