That's all you'll get is conflicting answers. The reason why is that everyone's driving style is different, as well as what you use your truck for. Some people can get away with putting the programmer on the highest hp setting, and not lose mileage. Others get better mileage on lower settings or even stock. There's no definite answer for you. You'll have to experiment and see which one works best for you.
