Just got in my new programmer. It's the edge evolution cs. Read a lot about different one and thought this was the best one. I was looking into programmers for some MPG improvement and for some power gains. Turns out the edge evolution's economy tune isn't available for my 2005 F-150. I just got it in so I can return the tuner. Should I or are the other programs worth the $370. All responses are appreciated. Thanks.
