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! The 7222-R includes a one time ECU unlock with purchase. Once you have the device you’ll submit the form on our website to send the ECU in for unlock, then you can tune with the Predator 2. *Does not support 2022 Refresh models*
