Your 2015 will have the better cams in it already. They used the earlier emission cams thru 2013 from what I've been told by our local dyno shop. They are unable to get good power from the 103's with the emission cams no matter what is done to the air box and exhaust. Fuel Motto told me the same thing when I bought the PV for my 2012 Ultra Limited and started tuning on it. I was still able to get mid 40's for mpg's, WAY up from the mid to high 30's it was getting before I started working with it, but it was never very impressive for power output anyplace. It produced a broad/flat torque curve, never really pulling hard anyplace, just OK.

Several of my friends have 2014 and newer bikes and with nothing more than a decent exhaust system and custom tune and cranking out good power number, and excellent fuel economy from their bikes.......Cliff

I went to a class at DynoJet about tuning with the PowerVision. The instructor mentioned that the memory on the PV could datalog for a couple hours easy. He mentioned that he would autotne when he would go on a weekend ride. He would do a 1.5 to 2 hour session.

I have done hour long+ tuning sessions in the past and never needed a follow up tuning session.

Just the other day I got a map from FuelMoto for my new headpipe & my other mods. Due to time constraints, and wanting to play with the powervision, I did one 25 minute autotune session. The average change was 1%. That was a pretty good canned map!!
