      Description

      Advanced Vehicle Tuner. The Livernois Motorsports MyCalibrator Touch Tuner is a handheld tuning device designed to maximize vehicle performance by optimizing horsepower, torque, and overall drivability. It interfaces directly with the vehicle’s ECU to adjust engine parameters such as throttle response, transmission shifting, and fuel delivery, enhancing both power and efficiency. The purchase includes one tow tune or one performance tune tailored for a stock vehicle, with additional multiple octane-level tuning options available.

      Construction and Appearance. Built with a durable plastic housing featuring a textured, non-slip finish, this tuner is designed for reliability and ease of use. Inside, it contains advanced electronic circuitry for precise vehicle calibration, all packaged in a compact design for convenient handling and storage.

      Installation. Installation is performed by connecting the tuner to the vehicle’s diagnostic port and following the on-screen prompts. No drilling or permanent modifications are needed. Users will require a Windows PC for firmware updates and may follow the included instructions to complete the setup.

      Application. This tuner is compatible with Chevrolet Silverado and GMC Sierra models from 2014 to 2020, including 5.3L, 6.0L, and 6.2L engines, and select 2500 HD/3500 HD trucks. Transmission tuning capabilities vary by model year and transmission type, with some vehicles limited to engine tuning only. Notably, certain 2019-2020 models equipped with 8-speed or 10-speed transmissions may receive restricted tuning coverage. Please verify vehicle compatibility before purchase.
