I will be honest, but the TQ curve on this graph does not make sense.
It is not possible to have to have the curve this flat with AFR all over the place. Looks like the scale on the graph is off. I see it is stretched some.

On n/a engine, afr should be around 12-13, and you're barely hitting 14. Try adding more fuel across the board, but less in the middle rpm band.

What is you injectors size?
