The Edge Juice with Attitude CTS4 is the ultimate inline performance module and digital monitor combination for Dodge Ram trucks equipped with Cummins diesel engines. Combining Edge's legendary Juice performance with the next-generation CTS4 monitor, this all-in-one system delivers substantial horsepower and torque gains, on-the-fly adjustability, advanced engine monitoring, and built-in safety features for daily driving, towing, and performance. Power gains and available features vary by model year and application.*
What sets the Juice with Attitude CTS4 apart is the ability to change between multiple power levels on the fly, allowing you to adjust performance without stopping to reflash the truck. Whether you need additional pulling power with a trailer behind you, improved response for everyday driving, or maximum available performance, the Juice puts control directly at your fingertips.
Built-in safety backdowns add another layer of protection by monitoring critical operating conditions and automatically reducing power when user-defined limits are reached. This makes the Juice with Attitude an excellent choice for Cummins owners who want increased performance while keeping a close eye on their truck. Compatible EAS sensors, including EGT monitoring, can further expand the system's monitoring and safety capabilities.
The Attitude CTS4 digital monitor provides real-time access to supported engine, drivetrain, temperature, pressure, and other critical vehicle parameters through customizable digital gauges. Set custom alerts and warnings, log vehicle data, monitor performance, and read and clear supported diagnostic trouble codes directly from the CTS4. Compatible EAS sensors and camera options allow the system to expand as your truck and monitoring needs evolve.
