Range Technology Pulsar LT Inline Programmer - 2019-2022 GM Gas Trucks 5.3L / 6.2L - 22451

The Range Technology Pulsar LT is an inline programmer designed for select 2019–2022 GM gas-powered trucks and SUVs equipped with 5.3L or 6.2L V8 engines. The module installs inline without modifying the ECM and allows on-the-fly adjustments to key vehicle parameters such as throttle response, tire size, gear ratio, and speed limiter.

The Pulsar LT can disable Dynamic Fuel Management (DFM) and Auto Start/Stop while maintaining factory ECM calibration. Installation is plug-and-play, requires no tools, and leaves the factory warranty intact per manufacturer description. The unit also supports clearing diagnostic trouble codes and reprogramming TPMS thresholds.
