Hope the winter has been good to you so far. How about an update on your 05 Silverado. I am very interested in a new crewcab truck for hunting and traveling. My old truck is a 2000 3/4ton crewcab LS with the vortec 454. I love the way the truck runs and rides but the 12-14mpg with a 26gal fuel tank means lots of stops on a trip. How has the 5300 held up for you and what kind of gas milage are you getting? Did you ever put a different tuning program in the truck?
