Hi everyone. I'm loving my M4 so far. I've had it nearly two months now. I've got a question. When I floor the car and it hits about 4000 rpms, there is a wheezing sound coming from the engine. The car is plenty warmed up.
Is this normal? It sounds like something is loose, there's a hole in something, etc... Could be the turbos as I have no idea what they are supposed to sound like as this is the first car I've owned with them. Anyone else notice this sound? Normal?

Thanks!
