What are the resommended performance upgrades I can do to my 2016 truck without doing any illegal deletes? Does anyone actually personally know someone who has been monetarily penalized for doing any deletes like EGR, DPF, or any other mods? From what I've been reading EGR failures cause some major coin repair, are there any aftermarket upgraded systems that work better? With all the immisions, do you see any gains from a DPF back exhaust system?
