I had the same issue with the 91 and 93 Aggressive tunes, got the same 3 fault codes, in my case I found my battery was reading 11.9 after staying overnight, I removed and fully charged it and made sure to discharge all power from the car before connecting it back, also I let the car do its learning process after connecting the battery and went ahead and upload the 93 Performance tune, since then the car runs pretty well and the issues I had with shifting from 1-2 and 2-3 are gone completely it shifts very smooth now.
