Its remapped and I've often wondered if the software is rigged to show a better mpg than its actually doing.

The distance (miles remaining) part, is a rolling calculation, based on the mpg you are doing at the time. So you could fill when your car is on a higher figure, and is not representative of your average mpg.
I'm aware some remaps/boxes seem to mess the OBC accuracy.
