The DiabloSport S1000 Sprint is a plug-in module that disables the factory Active Fuel Management (AFM) system so the engine stays in full-cylinder mode, and it also shuts off the Auto Start/Stop feature on equipped vehicles. On 2019-2022 GM 5.3L and 6.2L trucks it disables Dynamic Fuel Management (DFM) as well. The module plugs into the OBDII port under the dash and works without reprogramming or re-flashing the factory ECU, which eliminates the hesitation and exhaust drone caused by cylinder deactivation.
