So im getting my first truck and deciding to go with an older style powerstroke. What I'm looking for though is to get a lil better Mpg's. now before everyone bitches that if I want better mpg then get a car... No I have the use for a truck, and I don't want a gaser either. Anyway I planned on a cold air intake, and dual 12 inch stacks from pypes now for a programmer. Which one ? And should I get a touch creen with gauges built in or just normal with gauges on the dash? Need some help here
