I have a friend that says he always leaves his F-150 on the tow setting. That way he doesn't have to change back and forth. Is that OK to keep it on the tow setting?

 

As long as you aren't WOT all the time sure.

 

can you elaborate more darren? i have read that a lot of guys run level 2 (tow) for daily driving...

 

Yeah it's fine to run it though I'm not sure why you wouldn't want to be using WOT. The only issue I see is that it is a bit of a fuel hog tune and doesn't usually have as good of acceleration compared to a performance tune.
