So I've never owned a diesel before so please be patient with me. All of these EPA regulations make me nervous. Like you can't ever remove the emissions stuff and if you do dealers won't take one in on trade. The only thing I've done is unplugged the egr. Does this increase the chances of plugging the cooler? Can you put a tuner on without deleting and just disable? How much does deleting the egr system and removing the DPF cost? Truck has 143k on it and is stock.
