Add up to 136 HP / 291lb-t torque! Designed for Duramax owners who want more power, better throttle response, advanced safety features, and real-time vehicle data, the Pulsar V3 delivers emissions-friendly performance with a true plug-and-play installation. Take control of your L5P Duramax with on-the-fly adjustable power levels, allowing you to change performance at the touch of a button without stopping to reflash the ECM. Adjustable throttle sensitivity sharpens pedal response, while built-in safety features including Transmission Slip Protection, EGT Backdown, Cold Engine Backdown, and Shift Backdown help manage added performance under demanding conditions. The Pulsar V3 installs directly with the factory electronics with no cutting, splicing, or permanent wiring modifications required. Its standalone ECU-style technology delivers added performance while retaining the factory ECM calibration, making installation and removal straightforward. The CTS4 puts critical L5P Duramax monitoring at your fingertips with highly customizable digital gauges for supported engine, drivetrain, temperature, pressure, emissions system, and other vehicle parameters. Set custom alerts and warnings, log vehicle data, and read and clear supported diagnostic trouble codes directly from the display. Built-in Wi-Fi makes updates easy, while the Expandable Accessory System (EAS) allows you to add compatible sensors and accessories as your monitoring needs evolve. Whether you're daily driving, towing a heavy trailer, or simply looking for a stronger and more responsive Duramax, the Edge Pulsar V3 with CTS4 Kit for 2020–2023 L5P Duramax combines on-the-fly performance, adjustable throttle response, advanced safety backdowns, and next-generation digital monitoring in one easy-to-use system. More power. On-the-fly control. Smarter monitoring. Take Control with Pulsar V3 and CTS4. *When physically changing ring-and-pinion gears in late-model GM trucks, the factory cruise control will be disabled. While Pulsar can recalibrate the speedometer for the gear change, it cannot reactivate the disabled cruise control system. GM integrates this functionality into the engine calibration files, requiring full ECM tuning to re-enable cruise control.
