Unless you have the cams off a tooth, it's your program.
As I said before, I know nothing about the tuner you are using but it seems to me all the specifics are not aligned with your bikes parts.
See if they'll send you the map so you can have your dyno guy run through it for comparisons.
A TTS tuner will save you a lot of head-ache and about every shop is able to tune with them.

If your tuner thinks your bike has 5.3 injectors, the squirt of fuel will be a lot shorter duration vs if it thinks you have 4.3's. Could be the reason you're adjusting your air to fuel at 13/1 and the results are 13.8/1???

How well do the heads flow? The injector size that you tell the computer you are running will effect how long it keeps the injectors open but some guys will enter smaller injectors in the computer while running the larger ones to gain more flow when they are reaching the end of the duty cycle. I will say that a good tuning person got me over 7&7 while lowering my temps and increasing ridability. So in my mind its not the tool so much as the tradesman. I had my bike previously tuned by 2 different tuners. 1st guy got 7&10 over a canned map but she ran hot. 2nd guy didn't get me anything but she gained throttle response. 3rd guy was magic. Sepst was used all 3 times.
Change the fuel filter.

Don't recall exactly off the top of my head ... but, I think the fuel pressure out of the tank fitting is supposed to be 55-60 PSI range ...
There was an issue that was raised in the Dyna forum about pinhole leaks in the in-tank plastic fuel line ... chafing would wear a tiny hole ... it would divert part of the pressure back into the fuel tank, reducing the fuel pressure to the line out ...
Just an FYI as the fuel pressure question was raised ... don't know if this was ever a problem on the Touring models ...
