I have a buddy who owns a 2012 Cummins. We put on his exhaust and H&S and decided to go for a cruise I was in the ole stroke and we came to a four lane four way red light he started hitting the throttle and I decided what the hell lets roll. So we left easy and both punched it at the same time. I pulled on him pretty good and when we got back to the shop he said "I almost got your lil powerstroke" and i started laughing and continued to tell him my truck was only in Economy and the next time we will turn it up and make him feel really bad. We both just laughed. Its always good to have the other brand loyal ppl as your friends so you can see how things stack up.
