Since having my Scoobysport dp fitted (UK MY00) I've noticed a wierd fluttering sound under boost conditions. This isn't the turbo whistle as that it quite an obvious, constant sound (on boost).
This sound is louder and quite "uneven" ie. it comes and goes when accelerating. My boost gauge doesn't show any loss of boost with the sound and there's no obvious effect on performance, it just sounds wrong.
Possibly a bit of a vague description but does anyone have any ideas what it might be?

(standard car except for ss dp, magnex centre and WR bb)

It's wastegateflutter mate, nothing to worry about.

The cat, and the heat shields muffled those sounds before.
