i went to google and typed in: squealing noise from throttle body and up came a mustang website with a bunch of guys complaining about squeaking from the throttle body. They came up with the conclusion that you had to sand the edges where the throttle body meats the plenum, I'm thinking about trying this.

I did not install my supercharger so I don't know if there are sharp edges on the thing that the throttle body mounts to. Don't you have to cut something in this area during the install? the manifold?
