Do you have an O2 clamp? An O2 clamp will cure the stuttering during the vacuum to boost transition.

yeah, you probably need an o2 clamp. you're ECU is trying to keep you at 14.7 AFR as you are trying to add fuel....it should be worse at half throttle cruising between boost and vac and noticable when stomping on WOT just as boost is made.
