Edge Juice w/ Attitude CTS3 (31503-3) For 2004.5-2005 Cummins 5.9L

Edge Juice with Attitude CTS3 Cummins Tuner and Monitor

The Edge Juice with Attitude CTS3 combines an inline performance module with a powerful digital monitor for Dodge Ram Cummins trucks. This system supports 1998.5–2021 Cummins applications, delivering improved horsepower, torque, and drivability. As a result, drivers gain stronger towing performance and more responsive power during everyday driving.

Unlike traditional flash tuners, this system installs as an inline performance module. The plug-and-play design connects directly to the truck’s engine sensors and electronics. Because of this design, installation remains simple and does not require complicated programming.

On-The-Fly Power Control

One of the biggest advantages of this system is on-the-fly power adjustment. Drivers can change power levels directly from the CTS3 monitor while driving. This feature allows quick adjustments for different driving situations.

Lower power levels work well for daily driving and towing. Higher levels deliver stronger performance when drivers want maximum power. As a result, the system adapts easily to work trucks, tow rigs, and performance builds.

Advanced Monitoring with the CTS3 Display

The CTS3 monitor features a large 5-inch high-resolution touchscreen display. This screen provides real-time vehicle data and customizable gauge layouts. Drivers can monitor important parameters while driving.

The display can show boost pressure, exhaust gas temperatures, transmission temperature, and other engine data. In addition, the system supports data logging and performance testing. Drivers can review performance data and track improvements over time.

The device also includes built-in diagnostic capabilities. Drivers can read and clear diagnostic trouble codes directly from the monitor. This feature allows quick troubleshooting without additional scan tools.

Built-In Safety Protection

The system includes built-in safety backup features designed to protect the engine and transmission. When the monitor detects extreme operating conditions, the module automatically reduces power levels. This helps prevent damage during heavy towing or high-performance use.

An EGT probe is included with the system. The probe allows accurate monitoring of exhaust gas temperatures. Monitoring EGT helps drivers avoid excessive heat that can damage engine components.

Performance Potential

For trucks equipped with performance modifications, the system supports additional tuning potential. When combined with upgraded injectors, turbochargers, and other supporting upgrades, the system can deliver significant horsepower and torque increases.

Even in its standard configuration, the module improves throttle response and pulling power. As a result, drivers notice better drivability and stronger towing performance.
