Performance Tune On F150 2004 5.4 3v Engine

Ok i have a f150 2004 2wd with the 5.4 3v engine and i wanted to add a custom tune but i was just wondering if it will give a little better fuel mileage like the max hyper-tech power programmer …and about how much horsepower will it add to my truck on the 87 or 89 octane
