It does read high, and the reason is because they give their customers the Dynojet calculated estimate of what the Factory Pro dyno number equates to. Factory Pro measures true HP (which is typically lower than what most people are expecting to hear). When Xtreme first started giving out dyno results their customers weren't happy, so now they just give out the DJ calculated number. The true HP number that my bike peaked at was 109hp (green printout below). But even that is pretty healthy for a 600 based on what I found on that link to their site up there.

Nothing special about the motor, its just a stock donor motor with the same mods as up top (I just sent out my injectors to be cleaned and flow-matched over the winter). Fuel is just normal 93 pump. Tommy said the old custom map in there wasn't not done very well, bike felt rough and dead in the low and low-midrange.

To be honest I'm not really concerned with either the DJ or FP numbers, what I'm interested in is that sizable chunk of HP and torque that Tommy coaxed out of the motor all across the powerband but especially up top. I can't wait to get this thing out there and see how it feel anew.
