Okay I have a 2015 LML with a Def EGR delete kit. I used Anarchy diesel tuner. The issue I'm having is about every 200 miles I have to reinstall the tuner because the cruise control will not set above 60 mph. Once I reinstall a tuner it works fine for a little while. I contacted Anarchy and they claim it's not a tuner issue. I'm suspect of that because it didn't start happening until after I install tuner and the problem temporarily fixes every time I reinstall the tuner. Question is can I fix this with a new tuner and can it be downloaded from my computer into the mercenary tuner? And do you guys think I'm right about this possibly being a programming issue with the tuner?
