    I think there are other issues going rather than the tune.

    You should take a video while driving.

    is it possible its the trans locking and unlocking the converter causing the jerking?

    No its staying locked tach never moves when locked in.
    When the converter is unlocked (low speed driving) it will kinda surge at the very slightest amount of throttle, once the converter locks in then it jerks at very light throttle since it's locked. It even does it if you coast to a stop just not as bad.

    Could this be related to DFCO settings? Fuel injectors turning on and off?
