If you drive a modded derv hard, you'll use more fuel as it makes more power and therefore has the capacity to burn more fuel.
However, drive it smoothly and economically and you'll get better MPG than the standard engine would have, as it's more efficient.
Ball park figure for my stage 2 is about 42-44. And I drive it like it should be. If I fit my sensible head on a mixed run, I can see damn near 60. I've never worked out what I get purely motorway driving, as there's not enough road in the UK to use a tank up, unless you do some country road driving, and can never be arsed to fill up until the light comes on!
