My dad's bday is coming up and I was thinking of getting him a programmer for his 2000 K2500 Suburban 6.0. So far I've found the usual Hypertech and Jet programmers, but i want to find the best bang for the buck. He is looking solely for better mileage, as it only gets about 14 or so. Anyone have experience with anything else?
