Did you even setup the SAFC before you started the car? You need to set the SAFC up before you start the car.

your running 430cc injectors and the computer thinks you ahve the stock 320's. You'll be lucky to have a 8:1 a/f and im sure your coking the hell out of the exhaust and washing the cylinder walls with all that fuel. Maybe your AFC was set right but lost its memory, but regardless....TUNE THE SAFC and save your piston rings/lands.
