I'd try a different brand gas.

I've seen some cases where 93 with additives doesn't act like 93 without. Try it and see what happens. Your car should not be pulling that much timing. Doesn't sound like you're trying to give it too much timing. Try QT gas. Very high quality, the turnover in the gas in the tanks is good.

I've never had issues with shell before, but I will try another brand next tank and log what I find.

As far as I know, I should be commanding around 25° or so...

I ran QT gas a few times and it didn't go over well...
