The DiabloSport S1000 Sprint Module is the simple plug-and-play solution for GM drivers who want maximum performance without compromises. By disabling the factory Active Fuel Management (AFM) system, the Sprint Module prevents unwanted cylinder deactivation that robs your vehicle of power. For newer 2019-2022 GM trucks equipped with Dynamic Fuel Management (DFM), the Sprint Module also shuts down this feature ensuring your engine runs in full V8 mode at all times.
