I don't think you should have to tolerate destruction of engine mounts
just to have a rev limiter, after all, old L-Jetronics could do it without
even the tinest shudder.

It sounds to me as if no "soft" cut is activated before the full hard cut.
Can that be enabled on your system? BTW what system are you using?

As for "random" cylinder cuts; there are plenty of other ways of doing it
with almost no side effects.
