Good info thanks!
The only issue is getting tunes for my 2009 XB9 is very hard. Apparently there isn't a lot out there for my model. When the guy sent this tune he wanted to know how the AFV was after riding awhile. I was just happy to get a tune with the correct firmware and was hoping that over time I could learn how to tune and make my own adjustments. But like you said something obviously isn't right and it seems to run lean at idle. The front pipe started to glow after about 5 mins last night. Not sure if that's normal with these engines.
