the afr is good because the trims (stft and ltft) are trying to take care of it
Probably you also have the closed loop fuel control active during open loop if it s ecutek tuned

the trims are high probably because the maf scaling is not scaled properly.. Some tuners don't even try to have a perfect maf scaling, but they use a fixed one because they get predictable cells-choosing on the tune tables , or they have a speed density strategy, or they just don't care and let the ecu do most of the work

Difficult to say without a log from your car posted in here
