I'm sure this has been covered millions of times here, but there is no Gryphon programmer for the 2004 Expy? Couldn't a F150 '04-'08 programmer be modified work with the 2004 Expy?
The SCT's will work for the 2004 Expys, correct? What sort of power/MPG gains can be expected from a custom tune?
Thanks for your patience!
