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

I bought the programmer to recalibrate my speedometer. The previous owner swapped gears to 3.73 and didn't bother correcting the issue himself. I researched a few different options for calibrating the speedo and Hypertech's Max Energy Programmmer was the best option. The tuner was very easy to use. The only downside is the soft ware update. Immediatly after unboxing the product it requires about 25 minutes of installation and updating with a PC. I expected plug and play.
