I have read alot on here about the Spartan Tuner and delete. Most people are saying how great they are and how well they work. Is there anybody out there that has had a bad experience with one. I do want to get one but the warranty issue is my only problem. If something happens to the truck and has to back to Ford I have to take the tunes out and reinstall DPF. That is OK if I am around home, what do you do if you are out of state and break down and has to go to Ford. Any help would be great.
