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.

Interesting, I'm talking specifically about seeming ring destruction. Supposedly this is not just on tuned cars either.
