I'm 100% ignorant on how a tune is done. Is there just a preset library of fuel mapping that's uploaded or is there an actual computer program that is run that uploads your "maximized" fuel map? Also, is there a setting on such a program for "optimize fuel efficiency?"
you can have several tunes and switch from one to the other, up to you. But are you willing to sacrifice your 5 year drivetrain warranty for little savings in mpg? You may save a few hundred $ in fuel cost in 5 years but 1 minor engine or tranny work that is not covered by warranty nullifies that.
