Correct me if I'm wrong guys....(I know you will anyway) fekr.gif's, but it sounds like your diverter valve releasing the excess air back into the system when you lift-off off throttle.

Mine makes a lightly audible sound when you lift-off or change gear on boost and is perfectly normal, and yes, you could liken it to Darth Vader. grin.gif

When you next drive it, at about 3000rpm, lift-off the throttle and if it makes the same noise I would guess it's your DV and nothing to worry about....unless it's quite a loud fluttering duck like noise which means it's on it's way out, cheap and easy to replace however! 169144-ok.gif
