Running stock 4.10 gears and Nitto 37's on ATX slabs I average about 12.5mpg in town with only moderately aggressive take offs. I max out around 15MPG on the highway when driving 65mph with cruise cont set and no head wind.
I could regain pep, and I'm assuming be around 16.5ish MPG highway and about 14mpg city, if I would re-gear to my desired 5.13 gears.
Same setup here (3.6/auto) with very similar results. Just upgraded from 35s and only saw about a 1 MPG drop.
