cool!

sounds like turbo chatter to me but strange form of it. a front mount and inductionkit will sort that for you think you would need to blank off your dump valve to get it loud! just depends if your turbo can cope with it. i know the td05 can.

i will prob get told i wrong now. cant see what else it could be

wastegate chatter..

compressor surge.

aint wastegate chatter a myth?? its turbo stall aint it?
