I thought that the flutter sound was normal in a highly boosted car. Thinking about it this way:
-Boost tubes pressurized.
-Throttle plate closes, sending signal to recirc/BOV to release all pressure above manifold pressure.
-Recirc opens quickly, sending a low pressure wave out along the boost hoses
-like in a tuned exhaust this low pressure wave will return to the recirc which "could" cause the valve to close suddenly.
-this repeats very rapidly, causing the flutter sound. Bear in mind that this was my way of explaining the flutter sound before I had a full grasp of how everything works.
