IMHO if you don't need a diesel and you plan to leave it stock, I would sell it....too many expensive potential problems with this platform especially when it is stock and you are making short trips.I have a 2008 6.4 FX4. With my new job I am not hauling and towing much and have short daily trips. Regen comes on almost daily and hard to get a full cycle in.
What is your recommendation or suggestion for mods. I would like to have this truck forever!
I do have the Edge Evolution tuner set on economy but I get better mileage with it set to towing.
