I just installed my MM3 from Double R Diesel and uploaded the stock file, I'm all pumped up, had to post! My first Diesel truck (got it a year ago) and my first tuner ever. And we're gonna have a balmy 54 degree long weekend so perfect for working on stuff... I inventoried the Flo-pro exhaust, all parts there are ready to go! Jack and jackstands (and my son) ready to help me pull the DPF/SCR/DEF!
