Edge Evolution CTS4 Performance Tuner & Monitor | 2020-2023 L5P Duramax

Unlock additional power, improved drivability, and advanced vehicle monitoring with the Edge Evolution CTS4 Performance Tuner & Monitor. Designed for 2020-2023 Chevrolet Silverado and GMC Sierra 2500HD/3500HD trucks equipped with the 6.6L L5P Duramax diesel engine, this next-generation tuning system delivers gains of up to 125 horsepower and 275 lb-ft of torque at the tires while providing optimized 10-speed transmission tuning and real-time vehicle monitoring.

The included Edge Locksmith tool enables in-vehicle ECM and TCM unlocking without removing the modules from the truck. Four pre-loaded performance levels allow drivers to select the appropriate calibration for daily driving, towing, or performance applications. Adjustable Throttle Boost further enhances accelerator response, while transmission calibrations optimize shift timing, shift feel, and power delivery for improved overall drivability.

Featuring a high-resolution 5.5" touchscreen, the CTS4 provides customizable digital gauges, data logging, diagnostic capabilities, and access to supported vehicle-specific functions. Monitor critical parameters such as boost, EGT, DPF soot level, regeneration history, and fluid temperatures while maintaining factory emissions equipment. Compatible Edge EAS sensors and camera accessories provide additional monitoring options.

Important Notes

• A PC and Edge Update Agent software are required to complete the tuning process.
• Each device can unlock and tune only one vehicle.
• Once the ECM is unlocked and flashed, the vehicle can be returned to its factory calibration, but the ECM unlock process cannot be reversed.
• Devices become non-returnable once VIN locking and ECM/TCM unlocking are completed.
• Factory emissions equipment must remain installed and operational.
• Edge calibrations have passed in-house emissions testing; CARB Executive Order submissions are being processed. CARB approval should not be assumed until an applicable Executive Order is issued.
• Available parameters, functions, and accessories may vary by vehicle application.
