Us Nodak boys know one thing and thats wind! I helped a few buddies tune up their oil burners a few years a ago and found a comment pretty funny. I was on the phone with a shop in Denver ordering a few go fast parts and getting a custom tune set up. The shop owner asked what we were after and I said that we were looking for better towing performance and to increase mileage. I then said we don't need anything crazy power wise as we stay pretty local to our flat lands of ND, nothing like the mountains you guys gotta deal with. The shop owner laughed a little and said, the tuffest pull I ever had was in ND bucking a 30 mph head wind. At least in the mountains you eventually get to the top and get to go back down.
Its one of those comments that didn't strike me until I got off the phone. thought it was worth sharing.
