60+ is possible in a stock Hx
I shift @ 2000-2200 rpm and always accel @ 1-4 inches of vacuum (about 70% throttle). My Hx has a shorter geared Ex tranny and is costing me a few mpg's but my best has been almost 68 mpg
The real fun part is manipulating the throttle to stay in lean cruise.
With vg's, grill block, vx tranny, stock wheels with LRR tires, belly pan, rear skirts, deleted mirrors and wipers, MPGuino, throttle lock cruise control, and lean burn monitor I plan to hit the 70's with ease and maybe squeak into the 80's
