So, I have 2 white superduty f250 diesels. one a 2008 deleted crew cab with 144000 miles - the other a shiny new 2019 with 1200 miles. I've been spoiled by having an edge on the 2008 since 30k which told me when it went into regen- so far the new one hasn't given me a clue. how often do the 6.7 regen? and what is the best tuner/monitor to use on these?
