It's gonna be hard to diagnose this without seeing it. For one, it's
unclear exactly what the "opener reinforcement kit" is that you just
installed. But obviously that changed something.

It was a kit that had a much heavier piece of metal (the "standard
issue" was tin foil-G)that was bolted on between the top crosspiece and
the top two screws of the first hinge on the top panel.
Heavy enough to require tightening the springs a bit?
I wouldn't think so. It wasn't more than 1 lb if that. Just a
real (as opposed to aluminium) steel flange about foot tall and maybe 5
inches across. Would that cause the automatic door opener to "stutter"?
Rolled up and down by hand with no discernable difference.
