Have you thought about the possible increased MPG benefits, having a more efficient engine running a higher ron fuel ?
if you can increase the ignition advance safely at say 3krpm, without adding in extra fuel to help cool the cylinders, then you will gain power/torque and MPG.
its a win win situation.
