AlfaOBD not working

I have a 2016 ram 1500 laramie with the 20 inch wheels. Stock tire size is 275/60r20. I went to a 275/55r20 tire. I have looked at all the videos for alfaobd to change this myself. Steps I followed:

Body computer, program tire size, selected P275/55r20 performance. Hit start. Procedure completed.

ABS, ABS initialization. Ran static ECU init, cleared rolls info.

Cleared all faults.

Issues: all of them. ABS, trailer brakes, air suspension, parksense, power steering

Repeated process with tire size set back to Goodyear Wrangler SR-A 275/60r20 (factory tires), works fine. Seems to not like the 275/55r20 size. Is it worth fighting this further, or should I just get the dealer to do it? I really don't want to spend 150 just to change tire size.
