A thought to consider is that you are possibly in (Denver) at the mile high elevation and Fuel Moto dynos and provides maps with their elevation. I purchased PCV with auto tune and i am at 3600 ft elevation, i had lots of corrections in the map with auto tune and it runs great now. Elevation does have an effect on tune.
Good luck,

One more vote for a slipping clutch.
And for the suggestion about altitude, fuel injection isn't like carbs. With carburetors, engines would run better with different jetting. But FI does The only difference altitude makes is there is less power because there is less oxygen.
I ride all over the Rockies and the eastern plains, ranging in altitude from about 900 ft (eastern Kansas) to almost 12,000 ft. (Loveland Pass) Never had an issue with any of my bikes, just had to mentally adjust for longer passing times when riding at high altitudes.

If it was that rich, it should backfire like crazy and spit flames.

I mentioned that it may be rich because I have a power commander 5 from fuel moto map that did exactly the same thing to me and I'm at 3600 ft. My auto tune after installed and it made leaning changes to the map fixed the problem. It was 15-40 % throttle position on mine that needed leaning.

Iclick, do you remember your early posts about PCV and fuel Moto maps and how they are pretty much spot on? Then when you installed auto tune and went into some elevation you had hesitation and surging? Your report showed that the TP 15-40 had huge negative corrections at elevation with AT. I experienced the same thing and thought the OP described a similar condition??? I guess I missed the point, I do have auto tune corrections to my maps at elevation that fixed my hesitation then surging noticed especially when entering an on-ramp to freeway or roll-on passing.
If you could please clarify the difference for me so I can figure it out too, thanks much,

The OP stated; I would twist the throttle, then the bike would rev pretty high, take a sec or so to kind of kick in to actually speed up. Almost like it it was searching for the power band or something.
Sounds like when he hammers it the bike will rev a moment before the clutch actually engages.
