i just installed a turbo xs rfl bov on my audi. i cant hear it at all. i know i wont hear it inbetween shifts but even when i give it gas then let off i still dont hear anything. is this normal for auto's. a friend suggested maybe the bov is bad. if you run the stock bov atmospherically should you hear it? the rfl is supposed to be the loudest bov on the market i thought i would hear it even a little. thanks guys.
