    HKS F-CON

    Hey, this will be my first question here at SM. I am looking to buy a used F-CON with the stock 440cc ROM chip installed. I have the common Lexus afm / 550cc injector upgrade . I was told that there is a 550cc injector ROM chip for the F-CON. I dont' need that if I have the larger afm, do I?
