like the title says, I bored my throttle body out, and now it whistles ALL the time! Really loud too. any suggestions?

I have the bored t body also, but I think it was the helix power spacer I added that makes the sound. Mine is somewhat annoying also. I was told the spacer is not a bad add on but the helix part of it might be more of a gimmick. I thought about boring the helix part out of the spacer to see if that gets rid of the noise?
Someone else told me that the same set up with a closed air box might not make the noise. Mine is an open air filiment front and sides.

Bore the intake inlet to match, and the spacer if you have one. If everything is bored to match it will flow better, and shouldnt whistle.

this is a known issue with bored TB's. Everyone one i've seen on a 4.0 has done it.

If you were bored you'd probably whistle too.
