mpg increasing depends on what kind of driving you do...
If you drive 90% city you want a numerically high gear (EG: 4.56).
If you drive 90% highway I wouldn't re-gear.
You need to factor in how often you drive surface streets versus freeways, and what kind of driving you do (IE: speeds, acceleration etc.).
