Thanks for posting a 900 with all three mods, air/EFI/pipes. I am assuming that the dyno you posted is the "corrected" version since I do not see any references to humidity/elevation, etc. I am surprised that you did not post the sheet that shows the air/fuel. And since you have the PCIII that they did not adjust it to bring it more to their liking. But then again the curves are pretty steady and leaning the air/fuel may not have improved performance. Did the tech say anything about that?
So it looks like adding the EFI ($300) and pipes ($400-500) added 3 more hp and 3 more lbs/torque compared to just adding a BAK. Well you just confirmed that is $800 I don't need to spend....
The dyno for my bike also showed it running a little rich but not enough to hurt anything and checking the plugs 700 miles later confirmed that. Compared to my posted dyno is your 900 running richer?
