Okay guys I have to take my truck in tomorrow for warranty work. I removed the XRT program today and put it back to stock. I took the DPF/EGR off the truck...but the manual said to select "YES" stating the DPF is present even if it isn't. I just started the truck up and now the check engine light is on. Is that normal? I just wanted to put the truck back to stock setting since its going to the Dodge garage. When I put the 125 setting back in the truck and select "NO" stating the DPF has been deleted will the check engine light go out??? Any help is greatly appreciated guys.
