Ok one thing to clarify, AF Ratio does not control the "air forced into the piston". That is controlled by the throttle valve. AF Ratio injects fuel based on the amount of air measured flowing in.

As for maximum power, it's a combination of AF ratio and iginition timing. The key is to avoid detonation and leave a certain safety margin.
