However, we don't know much about even approximate distribution.
Unless pushed past stage 2 what failes would have probably failed under stock conditions anyway.

My timing chain and oil pump for example on 320i failed at 50k km, when I was still stock. Head gasket blown at 55k km, still stock.

I am tuned stage 2 since last 40k km, 0 issues.

Best regards

Fair enough mate.
