says they have had hardly any trouble with the turbo motors. Look at some Ford truck forums & see what's happening out there. I read somewhere that some guys are using catch cans for the pcv rather then running it thru the intake, to try and keep the intake valves clean because there is no fuel going thru the runners. I wanted a turbo Flex, but couldn't come up with one to build. I also have a 3k lb. camper I pull with a 6cyl. full size van & it has it's hands full with it, so I know where you are coming from. I wouldn't be afraid of an ecoboost.
