I have a ******d 2011 f250 and want to know about the different tunes my sct race tuner came with. It cam with tow, street, street firm, performance, and extreme. When I first got the tuner I just kept it in performance and never really used the extreme. But here lately I've had it in extreme which I actually get the best mileage out of.
So is it okay to drive it everyday in the extreme tune so long as I don't get on it and keep boost below 25 psi? What about driving it for 2-3 hours on the freeway, would that be okay since I get my best mpg?
Can anyone explain the differences of these tunes? I know it has to do with the boost pressure and fueling but which tunes do what?
