Driving the 80 around on 4.88s now...definitely more responsive. Have not gone offroad or into low range yet. Fuel economy so far about the same at 55 and below - 12.5mpg on average with the roof rack on. Too soon to tell at highway speeds. It still can't make it up the hill from Carson to Washoe Valley in 3rd at 65...so now I'll be even slower on the steeper passes, but on anything less steep than that it holds 3rd where it used to drop to 2nd. I like it.
