Should have nothing to do with your overall power.

If you have moosing bad, check that you have the most updated SVT Idle air control valve. There is a distinct difference between the SVT and non SVT IAC. The dealership accidently installed the stock non-SVT IAC on my car years ago and the moosing sound appeared. I figured out the problem and took it back to the dealer and they eventually put the right one on the car. Then the sound went away. With my Intercooler on I now sometimes get a little but ONLY when the outside air temp is very hot, and it soon goes away.
