    So Im in the process of installing kooks 1-3/4 headers and catted green h pipe on a 2013 Gt500. I have a JLT cold air, Ford Racing throttle body, 170 thermostat and colder plugs. It has a 93 octane Lund tune. Im told the tune will support the headers. Will re-learn after a couple of drive cycles. I dont race the car, its just street driven. Is this correct, that I shouldnt need to do anything with the tune?

    Someone let me know if I'm wrong, but usually when you get new headers you need a new tune. Who is the current tune from?

    You need a new tune especially on these newer cars. Your fuel trims will be off and probably a couple other things too.
