AFR is air/fuel ratio, which probably should be around 11.7:1 or close to it at that amount of boost.

AFC is Apexi's Air Fuel Controller. It's a device that adjusts the signals the computer reads to change the amount of fuel the computer adds (and the amount of spark advance - it is not capable of changing the two independently, unlike some more expensive systems).
