I just bought a 2007 silverado 1500 new body style with a 5.3l in it. I was wondering if anyone knew of any good programmers for these trucks. Id like to improve gas milage. I know its not going to increase a crazy amount but every little bit will help. Ive looked into the edge evolution programmer. Any ideas

No programmers for this man. They don't do as advertised. Look Into custom tunin from blackbearperformance or gowheatley.com. Or if you can find someone local who tunes and has a good rep. Gains will be much improved over a out of the box tune that's meant for every truck. No one truck is the same and a custom tune can dial in each truck to it's liking
