I just got off the phone with HyperTech support (800-352-3351). He said it’s the only Speedo recalibration tool for a 2022 through 2026 GM truck (Chevy or GMC). The part number is the inline HyperTech 77100 unit, currently $899. it is the same unit sold by rough country and summit, etc... corrects odometer and speedo along with Trans shift pints. He said it does not require removal when taking your truck to a dealer for service because it is an inline and installs under the hood as per the install instructions. It takes about 30 minutes to install for anyone once the controller is updated and programed from a PC for the tires used on the truck.
