I haven't owned a diesel truck in over 13 years and just bought a 2014 Lariat. The truck is a salvage repairable so I am coming to everyone here looking for recommendations and information as I repair/rebuild, and hopefully turn this truck into something I will want to keep for many years. Current state the truck has a No Limit EGR ****** along with their intake, and I believe a 4" exhaust. It is riding on 20" fuel wheels with 37" Mastercraft Courser MXTs and a 6" 4 link conversion. All of this leads to my first Question and I don't even have the truck yet. With the ******, intake and exhaust I'm assuming the truck must be tuned, but there is no tuner. What kind of problems is this going to create for me?
