I was not aware of 2020's seeing the ring issues fixed that is good. Do you per chance know what the actual root cause of lean conditions in cyl 6? I've heard from other tuners that it'll just randomly pull 5-8 degrees of timing from that cylinder normally.

No. There has been only one generation of EA839, with multiple applications. Like B58 in X3M40i and X5 xDrive40i.
The early EA839 issue was cam roller, not rings.
No idea on tuning and timing. The intake manifold is overly simplistic imo and air enters from one end and needs to reach the rear cylinders. I can imagine distribution is not the best in naturally aspirated mode. In max boost it probably doesn’t matter.
