The Edge Evolution CTS4 Diesel combines powerful, emissions-friendly diesel performance tuning with next-generation digital gauge monitoring in one advanced, easy-to-use device. Built for diesel truck owners who want more from their daily driver, tow rig, or stock truck, Evolution CTS4 delivers up to 175 horsepower and 470 lb-ft of torque while improving throttle response, turbo spool-up, transmission shift strategies, and overall drivability.* One part number covers hundreds of vehicle applications, including 1994–2022 Ford Power Stroke, 2001–2016 GM Duramax, and 2003–2012 Dodge Cummins diesel trucks. This extensive coverage makes the Evolution CTS4 an incredibly versatile tuning and monitoring solution across multiple generations of America’s most popular diesel platforms.* Pre-loaded Towing, Economy, and Extreme performance tunes make it easy to optimize your truck for the way you drive. Select the Towing tune when hauling heavy loads or pulling a trailer, choose Economy for everyday driving with performance and efficiency in mind, or step up to Extreme when you want maximum available performance. The Evolution CTS4 can transform the way a stock or lightly modified diesel truck feels from behind the wheel. More power is only part of the story. The Evolution CTS4 diesel tuner and monitor gives you real-time access to supported engine, drivetrain, temperature, pressure, and other critical vehicle parameters through customizable digital gauges. Configure the display around the data that matters most, set custom alerts and warnings, log vehicle data, and access supported diagnostic information. Whether you’re towing, commuting, troubleshooting, or simply keeping a closer eye on your diesel truck, CTS4 puts valuable vehicle information within easy reach. Installation is straightforward, with the CTS4 platform connecting directly to the vehicle’s OBD-II port. Instead of installing multiple standalone gauges, Evolution CTS4 provides a centralized solution for diesel performance tuning, digital gauges, diagnostics, data logging, and vehicle monitoring. Compatible EAS sensors and accessories can further expand your monitoring capabilities, while available camera options can add rear visibility directly through the CTS4 display. From a stock daily driver that needs a little more power to a diesel truck working hard with a trailer behind it, the Edge Evolution CTS4 Diesel gives you the control to make your truck perform the way you need it to. With a pre-loaded Custom Tune VIN License, it’s also ready to support custom calibrations from your favorite compatible tuner. Planning to upgrade to a larger turbo or injectors down the road? Evolution CTS4 comes ready to read and write custom tuning when you’re ready to take your build to the next level.* More power. Better response. Smarter monitoring.
