Maximum safe Highway tune

In about a month I'll be drivng 1800 miles to Ferndale Washington. Im very curious if someone has done a "Highway Tune" to maximize mpg and how many miles to the tank you got.

Obviously, It would have to be safe and not blow the motor up for going so lean and 87 octane would be nice to run as well.

So post up if you got something and tell us what you changed in the tune.

Probably help if you included the year/model/engine/trans info for the vehicle.
