Update:
A lot has changed since I made this post. I originally got it tuned by a shop in NC that came highly referred. I paid $300 for a 4 hour tune and although I can't find the chart, the numbers on his Superflow were 109/120 but with smoothing set to zero. I thought this was kind of weird, so I took it back to the dealership I did my baseline dyno run on and got back identical results. In the pic with two different dyno runs, the top run was from 2 years ago running the FM base tune and the bottom run was from after having it "tuned." So I contacted Jamie at FM and sent him the graphs and asked him what the issue could be, and he immediately asked for the tune stored in my Power Vision from the guy that tuned it. Jamie, very quickly, let me know "the only thing they did with our base tune is some basic VE adjustments, they disabled closed loop for some reason, and they never even touched the ignition timing or any of the other tables." After some back and forth with Jamie, I decided on going ahead and getting the HPI 55mm manifold and throttle body, put my factory o2 sensors back in it, and get it retuned by the guy who originally tuned my bike when it was cam only.
Just got it back. I am pretty happy with the numbers. Wasn't expecting an astronomical internet bragging right number and am just happy the bike is a lot stronger and runs a lot better now.
