Hi, i just recieved my first diesel and I'm trying to figure out what to do with it. It is an 06 6.0 dually with a crew cab. It has an Egr delete on it and an after market turbo. I'd like to see more horses out of it. I've heard things about the motor going bad after chipping them. Then on the other hand ive heard all sorts of things about Sct tuner being the way to go. Could anyone clarify? Ive also had thoughts about adding bigger injectors. What would be the biggest i could upgrade to without having to upgrade everything else. Would any of this put the integrity of my transmission on the line, it is an automatic. Thank you for your time, and consideration.
