Hello,
i had a skunk2 70mm throttle body installed on a dc5 recently. It is hooked up to an rbc inlet manifold that has been cnc port matched and an injen CAI on the other side.

It whistles at partial throttle and disappears at a bit more throttle or when i back off the throttle.
Has anyone experienced this ? frustrating as hell, please list or state the solutions you guys went through to sort this out.

thanks in advance
