I'm not a real big fan of dyno numbers because all of them read differently, who knows if they're corrected/non-corrected, etc. I like the drag strip cause that truly shows your power. If your riding skills aren't as good as the guy next to you, your MPH will still show your power, just your ET will show how good of a rider you are.
Its probably your weight. Your 100# heavier than the average rider. As mentioned earlier testers are usually around 150#. Also if your carrying more weight you're probably going to need the clutch mod.

Im sure that dynos will always vary somewhat....evenunder same conditions and such. Floridaliner I would love to do that! You let me know andare there bro! There is a track in orlando too. A new one.Not the Bithlo one, but an altogether new one.
The clutch is notorious as a slipper. Even a Warrior can toss out .5 off the 1/4 mile seconds with a clutch upgrade. Your not going to feel it slip, but it will cost you time. So if you are serious about shaving tenths off the time, I would think about the clutch, espesialy with your size.
