so a few months ago i installed a steeda cold air intake on my 2010 gt and they power difference was awesome and last week i installed a 62mm ford racing throttle body. like the change except now i have a constant whistling coming from under the hood when i drive with the pedal about a third of the way down. any suggestions on what this might be? i thought it could have been a loose binder on the CAI but i checked them all and tightened them all but its still there
