Weird sound when on boost

Hey all... Just a quick question, after taking my fd for a drive tonight I noticed a weird sound coming from around the turbos.. It kinda sounds like the stock BOV sound but a little more muffled and somewhat metallic(probably not a good sound). Has anyone heard of anything like this? It only appears when the car is under boost and it happens very low in the RPM range ~3500 rpms. The car still makes good power and the boost itself is normal.. any ideas??

Thanks,

Matthew Walsh

Is it like a "fluttering" sound?

If it's a mettallic sound while you're on partial throttle and goes away as you increase to maximum boost then it's the prespool BOV. You must have an open filter?
