Has anyone with a diablo sport moved there rev limiter up to around 7000?
Is it safe? What can the old pushrod run to before you start damaging things?

I don't know how high the LS2 will rev before breaking but since max HP and torque are reached well short of 6500 rpm, my opinion is don't go there.

I have a diablosport programmer. I would never move my rev-limiter up unless my valvetrain has been upgraded, stiffer springs, harder pushrods, retainers.
