Description
Enhance the performance, drivability, and control of your 2019–2021 3.0L Duramax with the Edge Pulsar LT – a powerful plug-and-play module that provides full control over key vehicle parameters without touching your factory ECM. This in-line module installs easily and lets you make critical adjustments directly from your steering wheel controls, keeping your factory warranty 100% intact.
Pulsar LT empowers you to fine-tune throttle response, recalibrate tire size and gear ratios, adjust the TPMS, and command important functions like manual DPF regeneration, high idle, transmission relearn, and trouble code clearing. Whether you're towing, daily driving, or running larger wheels, the Pulsar LT gives you the customization and feedback you need.
Important Note: Physically changing the ring and pinion gears will disable factory cruise control. Although Pulsar LT can recalibrate the speedometer, it does not re-enable cruise control or clear any related codes. ECM/TCM tuning is required for those corrections.
