20 questions

[MColeman]

I am reasonably certain that I want to send my FICM in to be tweaked and that I want to purchase some Rev-X. My questions are:

How do I find my FICM version? It is a remanufactured unit that was flashed to the "most recent Ford" calibration, according to the (eBay) seller. It runs fine and is a solid 48v unit - verified by Auto Enginuity.

Is there any benefit to an ECM rollback with the following calibration: VXDB1MZ TQBF0M2 ?

Custom tunes offered for SCT SF3? How do I order them? I cannot seem to get the link to work. I was considering the 40 hp Heavy Tow, 65hp Daily and (maybe) the 80hp Performance.

My Excursion is used primarily as a daily driver (60%) but I also use it to tow (40%). My main concern is vehicle longevity and fuel economy. Performance gains are always nice , but not my main focus (yet!). I cannot fathom why my buddy's f250 gets 16mpg (stock) while I barely knock down 14mpg (SCT "Street" (which is better than the 12.5mpg I got stock)).

Maybe not 20 questions, but it was a few!! Any input is appreciated.
