I think warmer weather produces better FE based on a few observations.

Warmer weather has these advantages vs. colder weather:

*takes less time for engine to reach operating temp.
*little/no idle time to warm up or because of snow conditions/traffic related to weather.
*warm weather will produce a warmer tire that will "self inflate" a few psi generally speaking when driven on a hot road surface vs. ice cold pavement.
*warmer weather people tend to take more trips/longer drives/routes vs. colder weather only driving from A-B with little time to warm the engine thoroughly.

There are probably more advantages but that's all I've got at the moment.

I bet his combustion would be more efficient if his engine wasn't fighting his modification.

WOW thats what I was going to write about next?

One thing I would like to add to the list is from the aero side of things.
Air density. Warmer air is less dense. So its easier for the car to cut through it.
