my TB was only opening 82% last time on the dyno. Looked like it dropped a cylinder after 5K and the tuner quickly let off. Adjusted the cable and it was good to go. Doubt this is your problem, but something to look at.

did your tuner lock the tune to 5000 for you to break it in?
ive heard of people doing that to insure themselves a little with warranty on a motor they just sold and tuned to avoid it coming back broke the next day.
but... i would think he might have told you about it, lol.
