Despite the fact that 14.64:1 AFR is stoich for gasoline, this is NOT where peak torque is made. Under full load, peak torque occurs around 11.8:1 and peak HP is closer to about 12.6:1. Cruise conditions are quite a bit different and can run upwards of 15.0:1 without technically being "lean", although again this doesn't necessarily equate to the best fuel economy or performance.
