    Default 20 MPG Highway YESSS.

    Hey guys. Just got back from florida and took my truck on its first little roadtrip. I make sure to fill the tank before I left and I clocked in an amazing 20mpg on the road trip. This is a HUGE improvement over my like 14 I get in the city. Well just thought I'd share my good news.

    I really like my Programmer. I got about 3 mpg increase city and quite a bit more power. I just like being able to change things on my own and at my free will. Things like top speed limiter, gears, tire sizes and things like that. If I was builing a race truck or muscle truck, I'd probly go custom tune but as this is my daily driver i'm totally satisfied with my Hypertech Max Energy Programmer.

    That is great mileage. Is your truck broke in yet? I will have to wait for a Hypertech as they havent made one available for the 4.3 V6.

    Yeah it's broken in. I've got about 12000 miles on it.
