Have you reset adaptations lately? That's one issue that causes this. The throttle sensitivity goes out of whack. Also, if you're running an MHD tune make sure it's up to date. I believe it was summer of last year they did some major updates. My car had similar issues which made it impossible to shift smoothly without throttle jerking and we lost burbles which all the teenagers complained about. They revised the tunes, corrected burbles, and a 5 min flash fixed everything.
