45psi of boost is too much with advanced timing. Prechambers can't handle that. One good example of the poor Mercedes engineering

Problem has serious effects, the faulty prechamber have to be replaced with a good one.

Um, they were designed to last many 100's of K on 13psi boost. 45psi is a little higher than 13psi.

What's the idea of this thread? It seems more like a rant than info.

same timing with ForcedInduction, thanks to internet and computer powers - i know now what rant means.

original editing:
sorry, i just thought someone with same kinda boost settings has problems... so, i thought it's good to know it's not a injector related problem, just a faulty prechamber.

not to rant, just to share info with you folks.
