I am considering the same thing. I don't tow often, and if I need to I can just flash it back to the factory settings. Seems like a pretty good idea. Have to gotten off the go pedal long enough to see any mpg improvements?
ill get back to you on that lol. Im currently running a 93 tune so im not exactly in economy mode
