I'm looking at either a bully dog or a hypertech max energy or payextra to get a superchipsprogrammer. I've gotan 06 4.8.Which would be better to get more power while possilbly helping mpg?

 

Option4 would be better, get a custom tune. But if your set on a programmer, thepredator seems to be the best.

 

Yeah, one guy on here is selling his Superchips programmer to get a Diablo Predator and another set his Hypertech to the side in favor of a Diablo Predator. Apparantly those are the best hands down. I'm planning on getting one in eventually.
