I have a 2007 Silverado Classic 5.3L V8. Im new to this whole truck thing and was thinking about getting a programmer. A friend of mine recommended the Hypertec Max Energy Programmer as well as the Hyperpac. The list of possibilities goes on and on. Does anyone have any recommendations that would work well with my truck that are in a decent price range?

Also I should mention that I put a 2.5in lift in the front a 1in rear as well as Toyo All-Terains (285/70/17). I also put in skyjacker nitro8000 shocks all around. Not sure if those specs make a difference in what I should get.

Thank again
Kenny
