Hey everyone, new member to the forum and diesel world. Purchased a 2015 Denali 2500HD. Truck just turned 12K miles. Hoping to enjoy this truck for a very long time. Looking for discussion/guidance on the Full Delete / Don't Delete topic. I have heard that deleting the truck will drastically improve the life of the truck , which is the very reason I purchased a Diesel , not sure were to begin.
