Hi Paxton888,
What Don mentioned in his response to you is correct; for things like a K&N filter, an airbox elimination kit like your Air Force One, and things like a cat-back exhaust system, we do not need to change anything inside the Superchip's programming.
In the case of headers on these F-150's & Expeditions, even then it's only required about 15% of the time, though we can always do a custom program for headers to get another 5 horsepower or so from them, so we always like to suggest having us do that custom program update for headers. About 15% of the time when you install headers on these particular vehicles (meaning the 1997 & up F-150 & Expedition with either 4.6 or 5.4 motor), that will lean out the motor a bit more than the system has the ability to compensate for. The symptoms for this could be detonation at higher rpms & heavy throttle openings, and/or the vehicle "nosing over", or stop pulling, after a certain # of rpms under full-throttle acceleration in the higher gears.
In your case, with the AF1 kit and a cat-back exhaust, that's generally fine; you don't need to have anything changed in your Superchip unless you start hearing some detonation after installing those intake & exhaust parts, and that rarely happens. If it does, we can always update it, but those parts don't usually cause a need for any compensation in these vehicles.
Have fun!
