I considered the obvious effect of the cooler air being denser, which is the very reason I wanted to see what improvement could be had.
Now if there is anyway to keep these temps during the summer, that would be a nice bonus.

One note everyone should consider for winter roads. If you have your shift firmness all the way up, watch for a sudden loss of traction if you're accelerating hard. I have experienced it a couple times already, temps in the teens or lower + cold tires = wheel spin (and instant fish tailing ). It didn't catch me totally off guard, though I was a bit surprised that I was shifting that hard; I usually don't feel it even when the roads have been slush covered.
Let's have a safe winter!
