SCT X4 Power Flash Programmer 99-19 Ford Powerstroke

The X4 Performance Tuner from SCT is the elegant and simple use solution for your desire for more power, flexibility and task focused performance. With the ability to store 10 custom ECM maps, not only do you have access to preinstalled dyno tuned maps to see out of the box performance gains, but you also have room to have your tuner add custom maps that fit your lifestyle and trucks personality. You have the flexibility to change not just ECM mapping, but also transmission behavior, from relaxed and forgiving shifts to "what just kicked me in the kidneys?", to adjustments to the electronic RPM limiter so you can lay out the perfect powerband for your application. Oh, and for funsies, if you need to let your rig stretch its legs at an approved venue, you can adjust the allowed top speed as well.

SCT's X4 also assists in diagnostics by being able to read your trucks diagnostic trouble codes (DTC) pointing you in the right corrective direction. With most shops being hundreds of dollars for basic diagnostics, the X4 can pay for itself rather quickly, all the while waking up the spirited warhorse your truck is meant to be.
