I recently bought a 06' LBZ CC & am wondering about a programmer. From what I've read, it sounds like it will be worth the wait for the Edge to come out. I am desperately seeking better gas mileage & its alwalys good to have a little extra power. I also am an absolute newbie to programmers & such. My questions are: Around how much will this edge programmer cost?-Do you need to have any other mods before you get a programmer?-Is it safe, warranty wise, to have this on your truck? Thanks all!
