6.7 (PSD) Kill
I posted this in the 6.4 forum too. Sorry if you've already read it.
Got a chance to race a guy with a deleted 6.7 PSD today. He was running Spartan with the war hammer tune, or at least that's what he said along with an intake and deleted stock exhaust. I was running the 300 Hott Damn tune. We ran from a dig and a 35 mph roll and both times I flat out punished him. From the dig, I pulled him by about 5 trucks up to 100 mph. He did better from a roll but still pulled him by about 3-4 trucks. Long story short, I'm pretty proud of this truck at this point.
