I really dislike the EX's program. It shifts like crap and gets poor mpg. I averaged 14-15.5 when I used the Stock Ex computer. Then I changed over to a Truck PCM. With a 04 F-250-F350 PCM and the PHP FICM I'm up to 17.5 so far...Winter fuel...
I have a summer of traveling ahead so I should have some good base numbers to report. Otherwise the EX is sitting in the garage, so I have not had much of a chance to do any real hard core mpg tests with it. I'd like to get to 20 at 75 mph, but it may not be possible since they're so heavy.
