Hi. First off. I know this will not work for everyone but it may help most. When the 6.4 does not get a complete regen or exhaust cleaning that causes multiple concerns. Mostly wasted fuel and poor fuel economy. Plus over time fuel contaminates the oil and causes premature wear. Especially to the rocker arms. The variables will be your calibration and gauge options. But if this works then you may have a way to tell if the regen process is complete or only partially done.
