Do a search,guys have removed the IAC and used a dremel to remove sharp edges.I had a 70mm accufab that did it but sold the car before I tried to fix it,mine did it under accel not at idle.

i've also heard drilling a small hole in the butterfly can help cut down on noise

haha yea i used to have the same thing with mine, but i didnt care cuz it was cool sounding. I learned that all it was, was the combination of the bbk tb and a CAI. Not a vac leak or anything. If you want it to go away, just turn ur idle up a little bit.
