    Default Best Silverado Programmer?

    Hey guys, Im a newbe to this forum, but not to trucks, I have a 2006 Chevrolet Silverado Z71 5.3 H.O, and was cringing at gas prices because I can burn a full tank up in not even a week my computer in the truck is saying AVG. Economy 17.3 MPG but I feel that is crap because I think im actually getting worse. I want to improve my Power as well as my Gas Mileage, What Truck Tunner is the Best for the 5.3 V8 I also just have a Magnaflow cat back! Also input as far as CAI would be great, Anyone have a Tunner? Thanks guys hope to learn alot from this site and meet some of you!

    Welcome to the site! The only programmer I've had experiance with is Hypertech and it was on a '96 350R. When I get through paying for my next fill up, I may look for one for my '04. Good luck!

    MPG in the 17's is actually pretty good for a full-size truck. If you don't trust it, just do the math yourself. But the DIC is normally fairly accurate. Otherwise just do a search for tuners, CAI, exhaust, etc. You'll find lots of info already out there. Basically, YMMV definately applies here. You may see an increase in MPG, a loss, or no change at all. The biggest factor being the driver, or course.
