Edge Pulsar V3 L5P Insight CTS3 Kit - 20-21 GM Duramax, Black

Edge Pulsar V3 L5P Insight CTS3 Kit for 20-21 GM Duramax

The Edge 22601-3 kit combines a CTS3 handheld display with Insight data logging for the 20-21 GM Duramax L5P platform. Housed in a sleek black shell, this kit is designed to sit neatly in your cab or engine bay while giving you a clear readout of how your truck is behaving in real time.

Designed for drivers who want more control over how their diesel responds and shifts, the Pulsar V3 L5P Insight CTS3 Kit offers a set of tunable features that can be toggled on or off as you drive. While not a promise of specific results, these controls provide flexibility to fit different driving conditions and preferences.

Key features you can adjust

• Transmission Slip Protection (On/Off) to help manage aggressive shifts
• EGT Backdown Adjustment to help monitor and manage exhaust gas temperatures
• Throttle Sensitivity Adjustment to tailor how quickly the engine responds to pedal input
• Cold Engine Backdown Enable/Disable to tune behavior during cold starts
• Shift Backdown Enable/Disable to influence how the transmission downshifts

Real-world uses and benefits

In everyday conditions, you can fine-tune throttle feel for a smoother daily drive or a more responsive takeoff. The EGT backdown option helps you keep engine temperature in check during spirited acceleration or towing scenarios, while the slip protection gives you an added margin of control during tricky shifts. The cold engine and shift backdown controls provide additional customization for engines still warming up or when approaching heavy workloads.

• Improve drivability during towing or mountain climbs with tailored throttle and shift behavior
• Choose moments when protection features engage to prioritize reliability over raw performance
• Leverage Insight data to monitor performance and trends over time
