    This looks like it's just a stock tune with AFM/DOD set to disable.
    Do you have a log file of it driving to see? Normally a lot of the throttle response will also be tied into the torque airflow models being dialed in properly, not just Throttle settings.

    Or If you'd like I can DM you some channels if you'd like to use for getting a decent log to use.
