I get that on my edition 30 without a remap, although the noise is very faint,
I never noticed it until the itg was fitted on my previous mk5
To me it just sounds like a very very reduced CAI noise is that simelar to what your getting ? - when you come of the
throttle at high rpm ? Im not worried about it on mine and id imagine it would get a bit louder after the map.
I think it sounds like it could just be a turbo stall noise mate, maybe worth checking out if you are worried though
