The word "tuning" has multiple meanings. When you ran a GDE "tune" for the Ram Ecodiesel called the "Hot Tune", you kept all the emissions equipment in place. The DPF and DEF were still intact and operable in the exhaust. The DEF injected whatever was in the tank but the sensors to monitor things were turned off. I injected water for 100,000 miles of ownership and avoided all the granular drying and clogging of the injector you put up with using DEF. Regenerations took place at a lesser frequency than stock because pilot injection was altered and the EGR was turned off. The EGR valve never opened. There was never soot in the intake, engine, oil etc. It ran clean so had far less soot and far fewer Regeneration. No "rolling coal" was possible with GDE - the best and cleanest of the"tunes".
In addition that "tune" provided a minor torque and hp increase along with changes in cruise control operation and more. With everything in place dealers had no clue as it sure ran clean and showed nothing to hint there was an operational change. Fuel mileage increased 1-3 mpg also. I would change my oil at 10,000 mile intervals and the oil looked literally brand new, not black soot-infested ink that you see with an EGR operation.
Now there was also an "Off Road Tune" that required total removal of the EGR system and DEF, DPF with the exhaust. That was a full delete tune with all the disadvantages of a full delete. Seems like most tunes for a Cummins are like that.
Sadly for me I do not know of a "tune' like the GDE Hot Tune for the 2019 Cummins. I have heard hints that something might exist but never found a confirmation. Seems like Cummins owners care little of clean-running, longevity, reliability and fuel mileage. Power seems to be the god and "rolling coal" a sign of their manhood. They pay big money for those full deletes, trash their warranties, foul the environment a bit and even make obnoxious noises claiming they like to be obnoxious.
Sure wish there was a version of a Green Diesel Engineering Hot "tune" for the new Cummins.
Going away on a hunting trip for a few weeks. Will not be easy for me to get on after tonight and see if someone has a hint of the kind of "tune" I am talking about. If it exists I sure would like to know about it.
