You will get a flutter type noise for several reasons. 1 is, the exhaust flaps are closed and you are accelerating with them closed (they will open on their own). To remedy this you can pull the exh flap fuse located in the trunk. The 2nd reason is, you have traction control on and you are pushing the pedal too hard which the ECM will come in and moderate your inputs which will cause a noise similar to a "flutter". I get this at events depending on which PTM mode i am in.
