Adding octane is an expensive option, is this a daily driver?

Reducing spark advance further is another option, it might
cost you some power, might not its worth a try.

The most logical option is to reduce the compression ratio,
normally when thy ping at high RPM, they ping at takeoff
you just don't hear it then. .
