These trucks are not good for a grocery getter, they're much happier on the road. The system is designed to be seemless, BUT, there's no way to know when a REGEN is occurring unless you have some additional gauges, I use an EDGE CTS 3, the CTS 2 will also work and is better in some ways, it will allow a forced REGEN, there is also SCANGAUGE 2, but it must have 4 or 5 lines of binary code that must be entered for the PID's for the ECO, SIMPLE programming but must be done fairly quickly due to screen timeout. The 80% or 90% message occurs when a number of REGENS do not complete, it only takes 3 or 4 incomplete REGEN's to reachthat stage. I set my EDGE monitor to monitor REGEN STATUS & EGT's plus 14 other parameters that I choose & think are important. I would recommend ALFAOBD & MX+ OBD DONGLE, an auxiliary gauge package such as the EDGE CTS & a stage 1 tune that will shut down the EGR if your local doesn't do emissions testing. If you do tune it I strongly recommend a transmission tune with the engine tune.
