All I can think of is you are hitting one of the limiters in the tune.

I know mine will do that slightly at half throttle...but never at WOT.

Could this be caused by the waste gate if it is not strong enough to hold the requested boost?

With the stock turbo, the stock wastegate can hold almost anything, or at least, it can hold way more boost to redline than you should be running. What your hearing is the compressor surge you could never hear before. There is a spot between bov opening, and throttle shutting and you'll get a little flutter. Its normal. Cyborg will do it without the 2J intake.
