Take a Focus ST, from what I've read they struggle to top 30mpg even on a run. But they do seem to be ideal for remaps and plenty of people have done it and claim they get similar MPG with improved performance.
So my question is: Would it be possible to remap a Focus ST to improve MPG but retain the original performance?
If so, what kind of MPG would you expect to see?
