    Did you ever figure this out, I have a 16 Mustang 5.0 that is doing the same thing and was looking for some info on how to prevent this as well

    I also had issues with the osc anti shuffle. Eventually gave up and disabled it in the tune and haven’t looked back since.

    There should be a parameter in the tune file to disable throttle oscillation and antishuffle.
