I (Herron Performance) will take vehicle and begin logging it and make the adjustments needed, just as most of the others that do it in person.

If you want to have dyno numbers I can arrange that as well.

With custom tunes picking up about 2-3+ MPGs is possible, depending on certain conditions.

And I will add that with some time with vehicle, the active fuel management can be changed as well to come in sooner and longer if that is what the customer wants. Just have to drive it and make sure the paramaters make for a smooth transition.

DFCO is also a neat thing (in some cases) but it also needs time so you can get the transition just right so it is seemless.
