Hesitation/ rough at 4500 log inside

I have been running a couple of different calibrations where this has happened. The Stock - Tuned calibration from Hondata and a custom calibration I am working on.
The log is from the custom calibration but I don't think it should affect results.
At 14:43 into the log you can see the rpm is fluctuating. It almost feels as if I am getting misfires.

Personally I believe it has something to do with the 50 degree vtc but I am not an expert.
Is it misfires?

The car is running lean. Are you using AFM or MAP for tuning?

It needs tuning. Short term trim is 15-20%, and the full load AFR is as high as 16:1.
