As Don mentioned you increase your mods they also increase your combustion temperatures. The temperatures go up and you need to lower your AFRs to supply enough fuel to that range, but also cool the chamber down. Less fuel, more heat. On a stock motor the levels are so low that a 13 is probably ok. In fact most ran closer to 13 than 12.

Additionally lets not forget that you can have a 11.5 AFR and still detonate based on timing. AFRs are only half the equation.
