Howdy,
It's a question that is really for my father. He just retired and bought a 2005 2500HD crewcab long bed and a 39' 5th. He wants to get more mpg out of his truck, but doesn't want to put any performance mods on for fear that it will void his warranty. I need to know if any of you have had any problems with the dealership and warranty stuff after you put on performace stuff, ie..Banks, Superchips, EFIlive, etc. Any help would be appreciated.
Thanks
