Should also mention the one I use is a programmer you just select 0 to put your truck back to stock in case you have to take it in to your dealer. I suggest you do that whenever you take it in or they will report to Ford that you have it installed. In fact one dealer reported that I changed the air intake and exhaust to Ford. I went back to that dealership and told them I would not do any more business with them because of it. It is funny because some Ford dealers sell them and install them make sure you find a good dealer. If you are close to Roblin Manitoba go see Hubert at Cardeager Ford he is a great dealer.
