Get ready for the ultimate performance upgrade for your GM Truck. Whether you have a Chevy Silverado or GMC Sierra, the Predator 2 is going to ramp up the performance on your truck in a big way! Running the Predator's performance tunes with 93 octane and you could see power gains of up to 45 Horsepower and 30 Ft/Lbs of torque for your truck without even popping the hood. The Predator's simple plug-and-play installation made it the longest-running legend in performance tuners. The Predator 2 comes pre-loaded with programs for 5.3L and 6.2L GM Trucks from 2019-2021! Not only does it allow you to install performance programs, but you also get a large bank of adjustable options that are critical for your truck- options like re-programming your tire size, gear ratio, and even removing the top speed limiter!
