A couple of observations though and hopefully someone here can clarify for me.
1. The map provided by Fuelmoto has changed considerably after a few tuning runs. I would have thought that my simple stage 1 would have been pretty dialed in to begin with.

wrong. what FM or DJ provides is a base starting calibration. You run the tunes to dial it in to your build/bike.

2. I've done the "compare" using WinPV and only the VE tables are changing. Should anything else be? Since there are still changes taking place, should I continue to do Autotunes or is doing a handful of runs sufficient?

you keep tuning until your VE tables are changing at less than 5%

3. Also looking at some of the other stuff, the AFR chart is basically at 14.4 across the board. It came set up this way...I thought it was supposed to be set at 14.6.

again, it's a base calibration. You can dial it in fairly close by using the street tuning method but for the best tune, an experienced dyno is you ticket.

2. My MPG is down a bit from stock. Is that normal? I was getting about 45 and now I'm closer to 40.

it will vary especially for the first few tanks of fuel you run through it. As with any high-performance upgrades though, your mileage will vary a bit from stock but you should be able to get it back to stock or even sometimes better with a proper dyno tune.

I'm not complaining about any of this as I really didn't know what to expect. I realize that I may be able to do better with wideband sensors and/or letting a professional tune it. However, the bike runs great and I feel more power and it sounds different (better). I'm just wondering if my results are in line with what should be expected with Autotune Basic.

yes they are. Keep tuning it until you have less than 5% changes in the VE tables and then call it a day.

Thanks.

When the changes are this small you just stop autotuning because it will always change a little one way or another.

So if I'm touring in the summer in Texas or the Colorado mountains, I should still be fine with this tune I'm establishing now in cool Seattle, or do I need to carry this PV along with me? Not looking for perfection on the road but I don't want to be causing any problems either.
