Mods to date:

I mentioned tank #1 was for "baseline" purposes. I'm about 1/2 of the way through tank #2 now (@ ~800 km / 500 mi.).

The only mods I've been playing with so far (and of course not finished) are grille blocking and passenger mirror replacement with a much smaller custom outside mirror + medium size inside convex mirror.

Grille blocking to date has been only with cardboard & tape. I have found I can block all but about 24 square inches (3x8) of the lower grille + all of the upper with no adverse effects (in my particular driving regimen - ymmv!), in the hottest summer weather
