Incorporate AFR target just applies a correction factor to the fueling so you can change your fueling by changing your AFR table, after tuning the whole VE table. All other settings have to be perfect for it to work correctly, especially MAT table and dead time.
PW = REQ_FUEL * VE * MAP * (Warmup/100) * (EGO/100) * (MAT/100) * (Baro/100) * (StoichAFR/TargetAFR) + accel + dead time
With it on, a well sorted VE table will vary little in boost as MAP climbs and steadily climbing VE numbers as boost increases can be a symptom of running out of fuel (pressure drop). With it off, the VE will increase as the AFR target drops.
