Strange stumble from 5,000-5,300 rpm

It pulls like normal at any other RPM.

I changed the plugs the other day, replaced an 02
Wires are only a few months old

maybe getting some KR? do you have any logs or no? maybe a misfire? loose wire? maybe the harmonics are just right to rattle a wire at those rpms??

valve flutter maybe, my z06 did that from 4400 to 4800 aprox.., a/f was correct and so was timing, turned out it was valve flutter because i got recommended the wrong springs.
