'08 Duramax tuner/programmer options?
Ok, my dad has a new '08 2500HD Duramax, and he's wondering about his options to get more power out of it with a tuner/programmer. Other than this all he has done is an MBRP 'catback', or whatever they're called on diesels since there are no cats.... lol. Anyway, first of all, will his warranty still be good with a tuner/programmer? I don't know much about that since I haven't had to worry about that with what I drive 
. He wants to keep his warranty good, and he also wants to get as much power as he can from it. So what would be the options, and in your opinion which would be the best for him?
Thanks for the help
