The DiabloSport Sprint Module allows for maximum power and vehicle performance by disabling the factory Active Fuel Management (AFM) feature that drops cylinders and reduces power.
The DiabloSport Marathon Module helps you get better fuel mileage by enabling your V8 engine to behave like a four-cylinder engine when cruising, while still allowing for full V8 power when you need it.
Easy installation. Just plug into the OBDII port under the dash and drive.
Compatible with GM vehicles built from 2005 to current that feature Active Fuel Management (AFM).
Eliminates hesitation on acceleration and annoying exhaust buzz caused by AFM activation.
Enables vehicles with AFM to stay in V8 mode at all times without reprogramming or re-flashing the vehicle's onboard computer (ECU).
Saves fuel by allowing vehicle to stay in 4-cylinder mode 80% of the time as opposed to only 35% from the factory.
