if someone can find a case of that causing turbo failure, i will eat my own hand
This is very true, and only happens during light decelerations. If you were to go WOT and shift you would not have this at all. Light decel will cause the flutter because you are not going to deep vacuum and the BOV does not open up right away. I have driven a few TT Z's as well, and can duplicate the sound in the audio clip heard here.

Correct as well. In order to have the BOV open fully the spring has to be overcome. If the spring is rated to at -18hg, and you shift at -10hg, there will be some flutter, naturally since the BOV did not open right fully.
