I am certainly no expert on busa tuning.
Does she run out of puff in all gears or only the top couple?
Could be blockage in the airway or partially crudded injectors.
If she screams in the lower gears but not in the top couple then it points to something dragging her back.
I've heard of this happening to high performance cars that use Optimax fuel exclusively. If you do, you could try BP Ultimate or Vortex Gold for a change and see if it clears.
I rarely get above 8500 in any gear except 1st to 3rd anyway.
