Well, after years of a hiatus and dreaming of having another Cummins one day, I am FINALLY putting in a special order for another! No it's not new, but I tell the guy what I want and he goes and finds it. It will be a 2013+, most likely will be 2015 or newer, Ram 3500 4 door or Mega. I've gone back and forth about the 68RFE or AISIN, but am not going to be picky, since there seems to be no tuning for the AISIN yet. Can't wait to dive into these forums and research everything I can, and ask a bunch of redundant questions . First off will be an emissions delete with 5" turbo-back, so if anyone has any input, let the suggestions begin! Happy to be back!
