yeah i set mine je 2618's at 50 over which is recommended...... but some have gone 35 and siezed the block trying to run tighter tolerances....

i did some reading and on the 4g63 forums they are running 65 over and saying fuck the knock..... just as long as there ems isnt reading over 50+ on there knock sensor at above 30% throttle.... whatever the fuck that means

im guessing as long as the piston slap goes away when i press the gas im good..... which it does...

but at idle...... shes slappin away.

when she warms up it quiets down a little.... but. yeah i still hear it. kinda like a loose rocker
