    2019 3.5 throttle help

    i have a 2019 f150. i have a tune here but im struggling with the thottle.

    if im coasting off the throttle at any speed and i get back into the throttle it feels like theres a big jump in the thottle almost like i punched it.

    and if im sitting at a stop light getting ready to take off the same thing. the throttle jerks off idle.

    the rest of the time its ok. help?

    I've had luck with changing the VCT distance table to retard the exhaust valve a little at around idle for helping with the jerkiness at takeoff. It might use a little more fuel idling, but seems to help with the takeoff.
    Engine>airflow>variable camshaft>Best fuel economy (under distance tables)
    Try changing the cells at 900 RPMs and .25 and .35 loads from zero to 2 or 3.
    A log would help out to narrow down the problem.
