Ford F250 Power Balance Loss of RPM contribution on cylinders 4 and 7.

This is a brand new truck with less than 5000 km. We have been back and forth to the dealer arguing the lack of power on this one. I was only last week, after six months of struggling, that we made a road test with a 6000 lbs trailer when the code came out on their engine monitoring tool hooked up while driving.

This is how Ford references this in their OASIS stuff. This is a known problem without any solution. This is what says the SPECIAL SERVICE MESSAGES #44156, 44155 and 32247 that they are referencing in the paperwork they gave me. I can email this to you if you need it.

This make my truck less performant than the old 5.4.

If you find a solution, please advise.

I am trying to have them to buy back the vehicule.
