In standard form you can get reasonable mpg out of it on a run(40-45ish), around town you'll probably see high 20's-low 30's. I think on a stage 1 you'll up that slightly, on a stage 2 like this you lose about 3-4mpg on standard, so I can get 40mpg on the motorway if I drive like a saint, and mid to high 30's if I'm sat around 70-80.
