What are you using to log the truck? Have you look into getting HP Tuners MPVI4? These ECU's have a ignition timing map and modifier specifically for ethanol content. The ECM (E92) uses cylinder airmass (load) x RPM to add ignition timing based on ethanol content percentage which is multiplier map 0.00-4.00 to control where it adds timing and how much it adds based on those variables. I have been doing a ton of R&D for my calibration company on the LT DI engines and these ECMs specifically. Getting fuel trims dialed in closer for the VVE and MAF calibration tables helps quite a bit in the response and drivability. There is quite a bit left on the table for sure.

It wouldn't hurt to get the module re-flashed. Usually only needed when module is replaced. There is a specific procedure to learn the steering angle to the module, that may be off now that the alignment is different. Usually only see it after replacing with rack, or module replacement and they throw DTCs when not learned.

The AFM disablers work okay, but sometimes they have to be unplugged from the OBD2 Port and plugged back in. It basically loops a can message the entire time not allowing the ECM to meet all the requirements to allow V4. If you are looking for a more permanent solution a custom tune would be better if not under warranty. Also keep in mind just because the AFM is disabled does not prevent a lifter from failing. It does lower the risk but does not completely eliminate the risk of a lifter failure. It does seem to make them last longer before failing though. I have a few customers who bought a custom tune from my company and still had lifter failures even with AFM disabled. A custom tune may cost a bit more than the AFM disabler but there are many more benefits, such at 2-3mpg improved fuel economy, better shifting, tcc slip removed to prevent premature torque converter wear, cooling fan settings, and better throttle response. It can be done remotely with a HP Tuners device or EFI Live Autocal. Just something to keep in mind.

Impressive mileage. Can’t wait to see you hit 200,000 miles. -

Probably not at this time on the HDs. They are usually 1-2 years refreshed behind the 1500s. I'm really surprised they have not at least shown something of them yet. It's only a few months left before the new model years hit the dealer lots.
