New guy here from GA. This is my first Duramax. It is a 2005, cold air intake, have a programmer, SunCoast Tranny, Raptor Fuel Pump. I got the truck about a month ago. I have put a 6" Rough Country Lift, Ranch Hand Bumper, 3 step side steps and toolbox. I'm still trying to figure out what all mods have been done to the truck. Needless to say, I will learn a lot from you guys.
