Instead of having to connect to a Windows-based computer for updates, the X4 has integrated WiFi built in that will allow update through a standard wireless connection. SCT introduced their latest flash power tuner that will replace the SF3 & X3 devices at the 2013 SEMA show in Las Vegas last november and now it will be finally available to the consumer in March 2014. One of the most exciting changes besides the better size and overall quality of the unit is the ease to update the device. SCT are one of the best names in power performance flash tuning software and over the years their SF3 tuner & X3 tuners have been one of the most popular and best performance flash tuners in the Mustang aftermarket. If you are looking for more Horsepower, torque, improved accelleration and overall improved performance from your 1996-2014 Ford Mustang GT, V6, Cobra, GT500, Mach 1, or Bullit you may want to invest in a new SCT X4 power flash tuner.
