I am new to this forum, I have been reading it for a while and wishing for an 06 lbz. I currently drive a ford but I really want to get back in a chevy. Anyway, I was at a chevy dealership and they said they could chip the truck and bump the hp up to 600 and to as much as 800 if I wanted them to. They said it would not void the warranty and that the engine was capable of it. What do you guys think? I would think that they would have to do a lot more than a chip, I think he was thinking intake and exhaust too. I didnt really get to ask any questions, a salesman I have previously bought from caught me when I was driving through and dreaming of a new truck. I appreciate any info and love this forum, lots of great info on it.
