I have a bbk 70mm throttle body and it whistles and idle is there any way to fix it?

grind this down, should help a lot
aftermarket MAFs tend to whistle as well

God I love seeing that kenny Bell everytime! in the magazine, the buildup. Just love it. My ProProd TB hasn't ever whistled. My luck I guess. But my bro's 65mm BBK Makes the wolf whistle everytime he drives.

Hello

I recently did a complete motor change. I had the whistling problem, This morning i came across this post, I then went and looked at my problem, My problem was with the BBK 70MM TB, And the IAC, I had loosened up my IAC and the problem went away. I removed the IAC and cleaned it with TB cleaner and put it back on, I had noticed that if the IAC is miss aligned a little, it would whistle, I have a new IAC on order.

Thanks tannerc91gt for pointing me in the right direction

Thanks
Mark

I got the whistling fixed. I had a 3" 90 degree. Silicone coupler on my inttercooler that was clapping at idle and was making my throttle body whistle.
