I have a friend that just bought a 6 door F650 that has a 5.9 cummins attached to a double overdrive allison auto trans. He uses the truck to tow large boats all over the country. He will be towing from 10,000 to 22,000 lbs depending on the boat/trailer combo. I have no experience with the VP pump motors so I am hoping someone could steer us in the right direction for the best turbo / injector and tuner combo.
