This simply resets the PCM to baseline settings. A reflash is the changing of settings by reprogramming the PCM. Have the PCM read and the flash version # noted. Find out what is the latest version issued Ford. The PCM will have to relearn YOUR driving habits after a battery disconect. The use of a programmer is a way of reflashing the PCM. The programmer stores the factory settings and flashes a new set of PCM instructions to it. Always keep track of your programmer in order to be able to "return to stock".

Have you had this truck for a long time, so you can really tell a difference from what it used to be? If not, than maybe your friends truck has lower gears in back then yours. That would make a difference.
