I agree with the guy that said it is just the CAI.

Its a combination of the cai and the tb/plenum. My freind has a 95 gt and right after he put the cai on it started to whistle a little bit. Then he put a new tb and plenum and it whistles like crazy now. I think it sounds good...but if you don't like it...ya ur gonna have to get a diff filter...or drop the size of the tb.

the only way to cut that whistling sound is to drill a 1/16 hole into your tb butterfly. but only do this if it whistles at idle. i have the same whistle sound with my 7m mm tb and plenum and i dont mind it.

Sounds like TB to me. I'd call the manufacturer's tech line to see if they have a suggestion.

BTW - I love the whine of the s/c!!

My friend suffered from whistles after he took off the silencer part, it pisses off because its load with the gurging sound from the exhaust its noisy...
just put on the air silencer

All I've done is remove the MAF screen & silencer and added a k&N cone and mine whistles now. Maybe its something along the lines of "sucking air through a swizzle stick?" or so I've heard of these cars...lol.

Im pretty sure its the CAI....

Ok I took a video its pretty crappy quality since its only a digital camera but you can hear the whistle... Listen closely because there is alot of other noises going on. But you can hear it mostly when I just coast... Im uploading another video too... I'll post it in a few...
