Well the Ford Dealer installed the Pro Cal Tune and the Ford Racing Intake and X-Pipe. It is all covered by the factory warranty so if they got it wrong for any reason than they would have to fix under warranty. They get your numbers off of your computer and than send them into Ford and a tuner is than programmed and sent to the dealership and installed by a factory Ford or Lincoln Mercury or a authorized Shelby dealership. I am super happy with the results and no fear of any warranty issues at all. By the way I still think that programmers and or Professional Tuners are very good at what they do and it takes along time for these people to gather there knowledge to be able to do what they do. I have alot of respect for these people. I just decided to go with the Ford Racing modifications. Thanks for the advise and good luck to you.
