Pulling my hair out

sounds like a stutter box a little . why would unloading the tires cause an engine to cut out ? I have had the old hemi car unload the tires before we got it sorted out years ago , and it didnt cut out ---??

I’ll go watch it again after a bit. I don’t hear any miss. Or any stutter. I just hear the engine gain and lose RPM very quickly.

You can’t see the rear tires are almost off the track after the first hit? A miss wouldn’t get the tires off the track.
