Hi everyone, new to the forum. I have used it a bit to learn more about my maintenance and mods for my truck. I have a 14 Ram 3500. I have the MM3 tuner and plan to purchase tune, and then delete in the next few weeks! 68K miles on truck and keep having issues with plugged def filter code! Im from MN, but wife, kids and I plan to hit the road in the spring and travel the country fulltime living in 5th wheel. So, want my truck as reliable as possible!
