Info

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)
  • Enables vehicles with AFM to drop cylinders in order to suit the driver\'s power requirements, while conserving fuel
  • Saves fuel by allowing vehicle to stay in 4-cylinder mode 80% of the time as opposed to only 35% from the factory
Some parts are not legal for use in California or other states with similar laws/regulations
