Finally got round to fitting a RS500 GGR induction kit to my car today and it now makes very strange noises.

it chips like crazy anything above half a bar of boost and sounds like darth vader breathing at almost every gear change.

i know the air box is a silencer but i didnt expect this much of an increase in noise

Also, why does the car chirp then dump??

Its a GGR dump valve.

any ideas folks??
