I used to get the best mileage w/ the Xt-Street, I could get 18 mpg on the hwy. I towed my bronco w/ the tow setting and liked it plenty.
W/ the newest tune version in the Xt-street i keep getting an overspeed code and it falls on it's face. It never got it resolved.
The last email I got was:
You can give Shane a call anytime during the day, he is our certified Ford tech that can help you figure it out.
With the SSC5 code, you are running the same program as everyone else and there should be no limiters at all.
Thanks

I left a few messages but I never got a reply and I"m tired of spending the $$ to send the SCT back and forth and then having the truck down for almost a week and a half.
On the other hand when I 1st got SCT, I seemed to deal w/ Eric each time and any issue was solved right away.
Fwiw, I currently use the Xt-X w/ race lock and I love it for DD, smooth delivery w/ almost no smoke at WOT. The race still has plenty fuel so I don't even bother.
As a whole you'll like it. If you don't have trac bars you should invest in a pair.
