I would not characterize the AFR in the upper rpm range as dangerously lean.
13-13.1 I believe is fine. Frankly, I would lean out that “sag” in the mid range and probably take out a bit of AE in the upper part of the AE table. I would try a bit more fuel in the top end just to see which way the power goes as a trial.

What was the SA for these run? Did u check for knock?
