Yes, that's correct. I mapped the part throttle fuel AFRs in the cruise and light load regions to run in the 15-16s which is leaner than 14.7:1, which is the stoichiometric mix the O2 sensor tries to adjust it to, disconnected the O2 sensor to disable it from readjusting the mixture, and added a bit more ignition advance in these leaner areas to compensate for the slower burn of a lean mixture.

I leave full throttle fuel and ignition tables mapped for max power, so when it's needed, just press full down on the gas pedal.
