Has anyone noticed that after putting in their FC TB that you hear a whistle from under the hood? Kinda like a turbo whine but higher pitched. Mine is being fed by a Steeda SRI.

I polished the crap out of the inner bore of the TB, that might have had an effect. Duno.

Yeah, that is fairly normal with different intakes. As long as there is no air intake leak, don't sweat it.

My intake never made that noise till I swapped in my TB... everytime I crack open the throttle, it makes a little whistle.

The type of filter you use also makes a difference.

I got it too with my injen, only after the TB swap... It could be a leak in the tb gasket...but I still get it even with no leak...I think it's pimp...but that's just me
