yeah it's very easy to agree haha. I've done the smart tune 3 times now. The bike works awesome but it could be that's its just my first harley. From my understanding though I can change the ratios manually, but the smart tune will bring them back anyway. Am i right in saying that?

One thing that really bothers me about the data is I have psi selected for units but it's still showing the a/f ratio in kpa. I have to convert myself because I'm used to psi.
Just did another log and the ratio is getting better but only baby steps at a time. Ive managed to reach 14.4 psi at cruise which is light throttle. Heavy acceleration is showing me 12.4 which is ok. I think a few more rounds and it should be dialed in.
As far as the tuner goes, it really takes its time, where as a seasoned tuner would have this setup in one or 2 pulls. I own a 2008 mustang gt that I installed cams and a supercharger on. No easy feat for tuning, but my guy had that setup in 3 rounds. Too bad he only does mustangs haha.

Pro street is from Harley. They will run lean. Because they are a manufacturer, and a lawsuit, they conform to eps rules damn the engine. Engines run cooler and perform better with a richer mixture and last longer too.

HD is under an agreement with the EPA to only go so far.
I just bought another bike, 2021 RG and I am reaching out to FM for information on tuning. It runs great but Im not happy with low end torque in higher gears. Im still adjusting to riding the RG but I think my 2011 RKC would probably eat it alive.
I dont want top speed, I want throttle response (torque) for passing and avoiding obstacles.
