    Default New 5.3 programmers...

    Wanted to get your input on what programmer to use to get the most out of my truck. Saving gas is a primary but I also want to be able to put up fights with Tiatns.
    Does anyone have any installed? What kind of gas milage do you get?

    I've got a superchips cortex programmer on mine, a buddy of mine had superchips on his dodge, so that kinda influenced my decision. Depending on what setting you have it on there is a definite increase in gas mileage, not so much now in the winter mind you doesn't help using the remote start so frequently either. . . but getting into a warm truck sometimes can be priceless especially when it is -30 C outside.

    It looks like you are going to be the test bed for milage numbers.
