I always see a lean spike (14-17) when I'm about to hit boost, then it goes rich. I didn't go past 4k during my last log since it pulled more timing than usual.
This is still the basemap FWIW.

Fb basemap got my rough idle and all fixed
My AFR was 11.2 on Wot
I think his basemap is good but you might have a mechanical problem.
I had no knock at all but my short Fuel trims at idle and crusing were maxxed out.
So imo u might have a hardware issue and be careful with that lean AFR
