Hey eco family I'm new to the diesel world so I've been studying like crazy to help keep my truck running strong. I want to say thank to Shaun with Mopar ecodiesel, rest in piece.. Your knowledge is golden and your reputation lives on! He had posted a video on the egr diffuser tube and the mod he'd made and needless to say.. It worked! Definitely not near as much sludge, carbon build up on diffuser tube. I did the mod at 44,000. At 45,328 got tuned and deleted the diffuser tube. Basically just wanted to give an update on what I've been doing to my eco but again I'm new to this so if anyone has any tips or ticks I'm all ears. I will upload pictures asap. (2015 ram ecodiesel tradesman) also just want to say thanks to the guys at sft for all the help!
