Keep in mind that the shop that did my pulls did not tune the bike so there was no incentive for them to show inflated numbers.
The air/fuel trace showed what the map was set at for 100% throttle cells and they did three pulls each. All three pulls on each run were with in 1 HP and .5 TQ of each other.

BM83: Glad you have enjoyed the development of your engine and observing the changes in performance along the way--nice information and don't recall anyone else doing it so methodically.
With your current build, a good tune will get you comfortably over 100/100 while retaining the flat torque curve.
I'm sure Coolhawg is very happy with his SE 255 cammed 96 numbers, but his dyno chart will look nothing like yours--his is a mountain peaking at 100 tq at about 4K and dropping quickly after about 4500, while yours will look like a plateau staying at or well over 100 from 2700 to abouat 5200, with more horsepower (which reflects how fast the engine hits those numbers).
