The Edge EZ with Insight CTS4 Kit for 2025–2027 Ram 2500 and 3500 6.7L Cummins combines serious plug-and-play diesel performance with Edge's next-generation digital monitoring. Designed for Cummins owners who want more power for daily driving, towing, and hauling without flashing the factory ECM, the EZ delivers gains of up to 110 horsepower and 280 lb-ft of torque for stronger acceleration, improved throttle response, and increased pulling power.
Installation couldn't be easier. The Edge EZ is completely plug-and-play, installs in under 10 minutes with no tools required, and requires no cutting, splicing, or permanent modifications. Because EZ doesn't flash or reprogram the factory ECM, it's also dealer-friendly and completely reversible. Simply remove the module to return your Ram to its factory configuration without leaving a tuning footprint in the ECM.
With five adjustable power levels, you can tailor the added performance to how you use your Cummins. Dial it in for smooth everyday driving, add extra response and torque when towing a heavy trailer, or select maximum available performance when you want the full potential of the EZ. The result is usable horsepower and torque that makes your Ram feel stronger and more responsive without sacrificing everyday drivability.
The Insight CTS4 provides real-time monitoring of supported Cummins engine, drivetrain, temperature, pressure, emissions system, and other critical vehicle parameters through customizable digital gauges. Set custom alerts and warnings, log vehicle data, read and clear supported diagnostic trouble codes, and expand your monitoring capabilities with compatible EAS sensors and accessories. The kit also includes a vehicle-specific CTS4 mount for a clean, integrated installation.
More power. Better response. Smarter monitoring. Take Control with EZ and Insight CTS4.
