    Default Cummins 6.7 Defueling for shifts

    Just need a bit of help here modifying a tune. I want to setup or try de-fueling on shifts for my truck to see how it runs.
    Is there any reason why some tuners may turn this off on their tunes?

    1:Limiters/parameters/ Torque by limiting fuel: Enable
    2:Set desired torque in: Fuel Limiter, Torque
    3:Set desired defueling in: Fuel Limiter, Table Selection 1,2???

    What does fuel limiting, torque control?

    It's on in my OEM tune but off in my race tune?

    To expand on what Les said, it is enabling the torque tables to limit the mm3 to stay below the maximum torque values. Also known as Torque Managrment.
