The SCT X4 has alot more tuneing capeabilitys I tryed a superchips flash programmer i needed to open up the speed limitor and the revlimitor plus i needed to tune for 25lb ford racing fuel injectors and a 80mm throttle body Superchips could not handle any of this after calling service thay told me that most flash programers are made for stock cars and engines I have a full race 9000rpm motor the SCT X4 will need a custom tune for the speed and rev, limitor the SCT X4 Has a injector tune built in
