Let's say someone was doing research on an EGR and DEF delete on a 2015 Cummins 6.7. That person also uses the truck primarily for towing between 5k and 10k pounds and has no desire to be a coal rolling Bruh kind of guy. The owner will install the actual EGR delete kit and turbo back exhaust, but has questions about the tuners out there nowadays. What said person is looking for is: Removing the EGR to prolong engine life A mild tune (60 HP or so) No NEED for a clutch upgrade Multiple tune availability (i.e theft mode) Easily updateable The truck in question will get a quiet exhaust (with a diet of course) and minor engine mods to compliment the EGR delete. With that being said, what are the better options out there?
