    Default programer. better mpg?

    Im looking at getting a programmer for my 2001 silverado 4.8 to try to get better gas mileage and a little more horsepower. I was wondering if anyone has tried these and how much better mpg they got. Also i was wondering about which one to get for quality and ease of use. Thanks.

    Do a search for my name and Hypertech. I wrote a nice little article on my experience. 25% better mpg and a great boost in performance.
