I dont want to start a huge argument but i am in the process of buying a newer truck. I need help deciding which Powerstroke to buy. Take into consideration reliability, towing capability, MPGs, tuned power, daily driver comfort, and price. I some times do really heavy towing like 28k combined weight and need something to be able tow that kind of weight. On the other hand I would like to take it to the track on the weekend and run a 13 sec 1/4 mile. I know that the 6.7l cant run 13 sec yet but in time it could as the tuning comes around for it. Any suggestion will be considered.
