Which tune do you run for max MPG

I was just wondering which tune do you guys run for max MPG? I'm STILL

waiting for Diablosport to add my vehicle but hopefully i won't have to want much longer. I want to have my gas tank full of the octane level required (87, 89, 91, or 93). Also i have to tow about 7000lbs back to Florida from Texas and was wondering which tune should i run for towing. I have a 8.1L 2500HD 4x4.

Thanks

Hulk

I don't change my tune for mileage or towing. Adjust injector slope and run with it. The only change I make is when towing and hot, I have my fans come on stronger sooner.

CANUCKPREDATOR - Do you run the 87 or the 91 tune?
