Custom performance is usually the best tune for highway driving but it varies from truck to truck and the conditions. If I plan on doing a bunch of driving over 55 mph I'll switch to my performance tune just because it has better passing power. Mileage for me is usually the same regardless of tune as long as I'm not having to get heavy on the gas pedal.
