What is this Noise?
I am hearing some crazy noise which sounds to be coming from behind me while I'm driving. It happens just after moderately hard acceleration when I let off the gas and the BOV lets the air release. It sounds like a bird making some type of mating call. What the hell!

Could be "Turbo Flutter" (Dunno why it would sound like it was behind you tho??)
When you get off the gas, the Turbo "Brakes" come on, as the vanes work against the air to slow the Turbo..
I couldn't hear it on my 13BT until I changed from the standard Air Intake to a K&N...
Cheers,
Dave
