I'm using map #1 from the Dyno website. The tech said I could do some minor tweaking to smooth out the curve a bit but it wasn't necessary as the air/fuel ratio seemed decently in order (sorry, no visual posting for that). Beyond that, I'm not gonna be able to give you too much more info.

Congratulations, you are the 4th 900 to post a dyno. Nice run and it is looking like we are finally getting some consistent results. So you are running Thunder Air/PCIII/stock pipes. Your run is very consistent with mine(BAK/scootwks pulley). You pulled 2 more horses and I got 1 more ft/lb of torque. What is encouraging to me is that the rpm range above 40 hp and 40 lbs of torque are very consistent between the two bikes. Yours is looking like 40+ hp from 4-7.1k rpms (mine was 3.9-7.1k) and your torque was 40+ ft/lbs from 2-6.4k rpms (mine was 2-6.3k). These are a much greater rpm range than was observed on the posted stock 900 dyno.
This also confirms to me that bang for the buck, of the three, air/EFI/pipes, changing out the air intake provides the most performance increase.
