The EGT should show a very slight increase. The higher the octane, the
smoother and cooler the burn. You have gone from 100 octane to
(arguably) 87 or 93 octane and the car gas should burn hotter.

I was under the (perhaps mistaken) understanding that mogas was measured
on a differing octane rating system, and that 93 mogas was ~100 octane
measured on the avgas system? (The question specified "premium" mogas).

Given that, I'd have thought everything would have been the same, across
the board.
