Hi! As the title suggests I am new to the world of diesel. I purchased a 2017 Denali HD this week and I have some goodies on order to be installed in the next week or so. So far I LOVE the truck and the power that she bestows whenever you breathe on the right pedal I am certainly not new to trucks and I have modified plenty or street-rods in the past, but I have a lot to learn about diesels. Anyways, I'm looking forward to the journey and expect to learn a lot along the way
