Hello; I was wondering if anybody can help me I have a 97 powerstroke and am trying to install a edge evolution. When I tried to install it it removed the stock program but would not install the performance program called edge they sent me a stock codeto get the truck running again and a new edge programmer that one did the same thing. They sent me a new one again and said it was my pcm going bad and would need to replace it. Ford told me that was not true. Can anybody help me with this. Thanks in advance.
