Power Vision Map
I agree that a competent dyno operator will always do a better job than a canned MAP...... The key is to get a competent or better dyno operator.... not everyone with a dyno knows how to use it well...
While totally anecdotal....
I have used canned maps from FuelMoto on three Stage I modded bikes, two Stage II (bolt-in cam), and two improved stock tunes. All those bikes run really well. I ran a couple auto tunes on a few of those bikes and they were all at 4% average change after one 20 minute auto tune session... that was with the Auto Tune Pro module and wide-band O2 sensors... That's a pretty good canned map....
I sent DynoJet the HD download tune from my 2003 Heritage with an HD 95" big bore kit I had installed 4 months after buying the bike new. DynoJet slightly "tweaked" the tune, and the bike ran like a totally different bike... in a very good way...
I later had a dyno tune on that bike when I changed cams again, during the tensioner upgrade. It ran worse than the HD big bore cams with a canned map.... go figure...
IMHO... For any vendor/salesman to make the blanket statement, " to never trust any pre-canned map from anyone," is total marketing BS for their product, a dyno tune.... It would be more truthful to say they believe they can make a better map on a dyno, than any canned map, rather than to badmouth all canned maps...
I trust salesmen who tell me what they can do for me, and why its a good/great thing... Not salesmen who bad mouth what other people do, attempting to convince you their product is better because the other product is poor...

If you're only at a Stage 1 or Stage 2, a canned tune and some AT runs will be all you need in my experience. Your engine isn't that far off from stock that the tuner can't make the changes and compensate for the fuel delivery. I tend to start with the canned tune then run several AT stacking them on each other. Run the AT, save it and load it in, then run AT on top of it. Rinse and repeat a few times and you'll be good to go in most cases.
Spending the coin on a dyno tune for the Stage 1 or Stage 2 isn't without value, but the returns are diminished compared to tuning after a major overhaul.

Even with target tune, you think I should stack some auto tune runs? I suppose it would give the target tune a better base to adjust from.🤔
I dunno, maybe Im putting too much faith on target tune to get me there from wherever.
The Best of Harley-Davidson for Lifelong Riders
I have no personal knowledge about that dealership or those tuners, they could very well be the best dyno tuners in the world...but...
My experience has been that the best dyno tuners are NOT in dealerships... at least they don't seem to stay at dealerships very long... I knew two very good tuners at dealerships, but only for a short time... One opened his own performance shop and the other went to work for an independent motorcycle shop...
Current dealerships are set up to push bikes thorough and make money.... A good dyno tune is not a "cookie cutter" proposition. While some go together relatively quickly, some need time to work through.... I just don't see dealerships supporting tuners who take the time to get it right, every time... Additionally, since the EPA Consent Decree, and all the fiasco over EPA tuners, and tunes, along with the reporting requirements, most dealer tuners have been doing EPA approved tunes for the last several years... That's not the experience base I want in a tuner...
I would talk to some independent shops who do NOT have a dyno. Ask who their "go to" dyno shops are for their performance bike builds... Also, talk with any friends who have had dyno tune experiences....
IMHO, while nothing's 100% perfect, word of mouth recommendations from people who ride and/or build performance bikes will be worth more than any "certification"....
Good luck with your tune....
