2020-2022 Chevrolet/GMC 2500/3500 6.6L Duramax Pulsar LT

New In Line module that offers complete adjustability for many of your truck features all from your steering wheel controls. Does not modify your diesel trucks ECM. Pulsar LT lets you adjust throttle response, tire size changes, gear ratio changes, TPMS, and your trucks top speed limiter. You can also run a manual DPF regeneration cycle, transmission relearn and adjust high idle function. Connects directly to your trucks computer system and installation is a breeze which leaves your factory warranty intact.

* When physically changing ring and pinion gears in late model GM trucks, the factory cruise control will be disabled.
