Pulsar LT for 2019-2022 GM Gas Trucks

Description

Take command of your GM truck’s performance with the Pulsar LT, the ultimate inline control module designed for late-model GM applications. Engineered for seamless integration, the Pulsar LT installs directly into your vehicle’s computer system, no tuning, no permanent modifications, and no hassle. With this innovative device, you can adjust throttle response, tire size, gear ratio, TPMS settings, and even enable or disable features like Active Fuel Management (AFM) or Dynamic Fuel Management (DFM) in seconds.

Increase efficiency and performance with Range Technology AFM/DFM and Start-Stop OBDII controls. Range Technology specializes in advanced electronic solutions designed to address Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) systems found in modern GM V8 engines. Founded to solve real-world drivability and reliability concerns associated with cylinder deactivation, Range identified the need for a simple, effective way to keep engines operating in full V8 mode without invasive modifications or custom tuning. Range developed plug-and-play devices that interface directly with the vehicle’s onboard diagnostics system, intelligently preventing AFM and DFM activation while preserving factory calibrations, emissions systems, and vehicle safety features. These solutions help eliminate unwanted transitions, improve throttle response, enhance exhaust sound consistency, and support long-term engine reliability. Engineered specifically for GM V8 applications, Range products are continuously updated to support new model years and powertrain configurations.
