This adjustment will close the valve a bit sooner, and provide more cylinder pressure.

Octane booster may actually hurt power. IDEALLY you want to run with only enough octane to limit pre-ignition (ping), any more octane will reduce power since higher octane fuels usually have more resistance to ignition than low octane fuel. Higher octane means less chance of ignition do to compression forces/heat, lower octane fuels have less of this additiive to limit ignition till the spark
FWIW; Engine guy just confirmed my CR is 10.5:1. . .
