it seems that the car is at it's best at stage 1 when it comes to fuel econemy.

stage 2 , greens , 3bar, std. turbo should use more fuel.....

with the same kind of driving like on a highway would the car use more fuel than at stage 1 ???

I'm really interested in figuring out if it's gonna be more expensive to drive (under the same right foot load )
