This is a must need tuner as this tuner really works. The GT Gas and Diesel tuners unlock more horsepower and torque to meet the unique demands you put on your vehicle. With preloaded tuning, customizable gauges to track performance, and a wide variety of hauling and off-roading features, you’ll have plenty of power to take on tough jobs or improved fuel economy for long highway hauls.
Had used on GMC 2500HD and used the tow mode mostly. Helped with performance when towing a fifth wheel trailer and was able to average 22 to 25 mpg when not pulling trailers.
