big deal it whistles. its sucking. your CAI increased the flow and is most likely made out of metal so no sounds canceling like plastic or that big air resonator piece

mine did that stock.

Now that it has a louder exhaust it doesn't seem to be much of a "problem" anymore.

That was my thought, i haven't really thought about it anymore, guess I'm used to hearing it and don't pay attention

kind of off topic but while i was searching found this... I just got my cam installed yesterday and now it whistles? could it just need to be retuned? the truck drives fine other than it needs a retune.
