I am going with the Granatelli cold air system that you suggested. This should do what I want and my Dallas Mustang contact has explained everything about the reflashing and there should not be a problem. He said that if my dealer gives me any grief over anything that I should just call Ford and they will set him straight. Apparently if I do not break into the motor and just add on bolt on items they cannot say anything. I need to call Ford anyway since my sales person wrote his name and phone number on my window sticker.
