I have a 2018 DD RT. Does anyone know how to do a throttle body calibration?

Unless you have a programmer and flash it to your personal preferences, (and don't ask me there, as I never have done that) , the only way is have it calibrate itself while driving after a reset (Disconnect battery, touch pos cable to frame, reconnect battery).

It relearns through idling in the driveway long enough to "warm-up" -- maybe 10 minutes or so, then taking out for a 10 mile or so drive.
If it hasn't straitened-out by then, I would recheck for codes because it should've. Unless the hardware is still "amiss".
