If your ltft is over 10% under load and the commanded AFR and measured afr are way off then something is wrong. If maf scaling has been done correctly ltft should be less than 5% or possibly less than 3% under load.

did the cel come back after ecu reset

check for air leaks on intake and that maf sensor seated correctly and is clean

Do you have ecutek map switching ? are you on correct map, you did not switch back to stock map of something ?
Okay ill get those logs stat. Cel did not come back, but code came back as "pending". I do have map switching, but they are all the same tune with various racrerom features afaik. I have never actually switched the map.
