Ive been thinking about timing more. If I could run about a 13-13.4 AFR at wot (Which Ive heard makes the best torque and going richer than that is just to lower egt's)

So i wonder what would happen by running about 3-5 degrees less timing at wot and running about 13-13.4AFR. Becuase at that afr I don't think you would need that much timing becuase the burn rate is faster.

I don't even see why the richer mixture makes more torque than stoich? Isnt anything richer than stoich just going to be wasting fuel? Ive heard that the slightly rich mixture ensures that the all the oxygen molecules are used for combustion. But why wouldent they all be used at stoich? Is their not enough time for complete combustion at high loads and rpms?
