maybe the dumb valve that is making the noise, 300 sounds about right, just get a scooby specialist to check the car before committing with cash

Mate, if its Turbo charged it has a Dump valve, sits between the turbo outlet and the throttle body. Just not one that makes a silly noise!... well actually in this case it does
