Offroad tuner or the street tuner. If its the street tuner you are going through regeneration, especially if you have that stock exhaust on it. It gets dirty faster
IF its cold outside your truck will also high idle, but i wouldnt think it would since you just drove unless its super cold.
Offroad tuner......make sure you have all the updated firmware and software....and that you also are on the DPF deleted tune if you have done this mod...if not you better get to reading on here and turn your truck back to stock. You will have a lot of Regens running the tuner and no other supporting mods.
