Any of you guys ever use any programmers? I'm thinking of getting one to get a little more out of my 4 banger. I know my friends Chevy with the 5.3 got 35 more HP and 3 mpg after he put one on. I know I wouldn't get that much with the Lil 2.3 duratec. I would be happy with around 10-15 more HP. I really want one that can change gear ratio, speed limits, and tire size too.
