at 20 mpg, something is really wrong unless you are just full WOT all day every day. I would load a zero map, zero out all the settings (accelerator pump, warm up enrichment etc...) and see if it gets better. 20 mpg sounds like the previous owner did something very stupid with the powercommander.
no you do not need an autotune to load the map, just the pcV it self. Even if you had a powercommander 3, you could still run the pcv map, you would just have to punch in the table manually and interpolate some of the cells....
