Bully Dog GTX Performance tuner and monitors are the next generation of performance tuning. Want to unlock your truck's true potential? GTX provides street-tested, dyno-proven tune files that are the key to opening up your ride's performance. These easy-to-use units—no computers necessary—feature 5 in. capacitive glass touchscreens that display graphics and gauges in brilliant HD color, in addition to starting up incredibly fast, and providing an ultra-responsive user experience. The GTX tuner/monitor comes standard with a convenient "grab and go" magnetic mounting system to keep your device front and center while driving—and removes in seconds when not in use. Loaded with powerful features and their most advanced hardware to-date, the GTX performance programmer has the ability to hold 20 custom tunes and comes preloaded with multiple Bully Dog tuning levels. They also allow you to monitor an extensive list of PIDS, or engine parameters—as well as log vehicle performance data as you drive, and play it back later using Bully Dog's free LiveLink software. Moreover, you can read out and clear Diagnostic Trouble Codes (DTCs). Finally, for those who want to take their truck to the next level, GTX can receive custom tunes via Wi-Fi from any of Bully Dog's custom tuning dealers around the country.
