Overview

It is compatible with 2020-2023 Chevy Silverado and GMC Sierra 2500HD/3500HD models equipped with the L5P Duramax Diesel engine.

This module allows for calibrations beyond the range of standard programmers, catering to vehicles where the computer does not natively support tire size or gear ratio adjustments. Installation involves connecting the module to a PC via USB to input new tire height and/or gear ratio data, then physically connecting the module inline with the instrument cluster connector.
