When I actually go wide-open throttle, the induction noise is continuous and sucks very hard. If you listen closely to my video you can hear the induction sound from the intake and that slight choppy sucking sound.
It honestly sounds like the same phenomenon as I am getting. Your's is higher in the rev range so the oscillation are happening faster mine are between 2-3k so happening slower. Some of the difference in sound I'm sure are from physical differences between our intakes. And the MSR intake noise is probably one of the loudest out there.

This does not occur for me on the stock map with the intakes. So it's something with the map, probably from the increased boost across the entire rev range.
