With an AFC you compensate for 650cc injectors by leaning out the low and high throttle by 30%. So the AFC interupts the signal from the MAS going to the ECU and lowers the signal amount by 30%. With the MAFT, you set the dipswitches to 650 injectors, and it interupts the signal from the MAS going to the ECU and lowers the signal amount by 30%. They do the same damn thing, the MAFT isn't any better or safer than an AFC, it just lets you run a GM MAF instead. Unless you change the code directly inside the ECU, you are just tricking something somewhere.
