Debating on getting afm tuned out on my 2014. What kind of fuel mileage are you guys seeing without afm?

No real difference around town. 1-2 highway depending on speed, wind, hills, etc.

That's about what I was figuring. You running a handheld tuner or custom tune

Had a custom PCM and TCM tune done using my DiabloSport Intune device By Lewis Eaton (DiabLew)

 

AFM deactivated, Catless exhaust, etc along with other things for the Transmission Tune

 

Im very happy with it, and I'm happy with my Gas Mileage

I have a Diablew 87/89 custom tune. AFM off TM off. I don't do enough highway driving to tell any difference in mpgees. FYI, if you plan on ever getting exhaust, you will defiantly want do delete your AFM because you can hear it kick in to V4 and it is super annoying!
