Yup... bouncing off the rev limiter is no good. Stock rev limiter is a fuel cut, which can most definitely cause some detonation. Chances are you just blew a piece off of a piston, but I kind of question your idle up like that. Mine ran just fine when I was missing a chunk of piston.
How can a fuel cut cause detonation when there is no fuel to detonate or pre-ignite?

I've seen Fitz' motor idle like crap when the SOHC piston lightened up itself, yet ran like a champ under boost.
