You can call me French
There is a guy that goes to my church and would like to delete the DOC/DPF. I was wondering if you could do the delete and not run a programmer? He wants to keep the truck as close to stock as possible so he doesnt void his warranty. I know that deleting the DOC/DPF will void the warranty, but can't you just put the stock system back on if he had to take it to the dealer? Forgive me if I'm asking dumb questions, I'm still learning the 6.4L.
