The afc will do the same thing that the SRT ECU does but I believe the S-AFC has more adjustability. One advantage of the S-AFC is that when you add the header, exhaust, race pipe, etc. (like you said) then you can adjust it to add the max power with the entire setup. As for F/I, you may be able to use it for the S/C kits, but it is unlikely that you will want to use it on the turbo setups.rllinghardis300 said:From what I've gathered the SRT Intake comes with a mapped ECU piggyback. Thats where the gain is produced. With the Injen and a S-AFC, can the results be achieved as well? With the S-AFC, adjustments can be made for exhaust, headers and race pipe. Are my assumptions correct? I think I posted a question regarding the use of the S-AFC in the event of F/I. Is there a use for the S-AFC when one does join the F/I ranks?
