I think there are a few of you on here running the 2015-2017 Ram 5.7 and 6.4 Diablo i3 Tuner & Unlocked PCM. I know nobody is buying these for MPG but has anyone played around with the MPG Booster on these to see a 2-3mpg boost? It would be nice to go from ass kicking mode to a mileage boost for just daily driving.

Get a custom tune. It will get better mileage than stock on a performance tune if you drive with some sanity.

Yeah with all my mods I get about the same mpg I did stock with mds. Mines shut off with the tune. Have been thinking about turning it back on to see the difference it really makes

Yeah I was planning on it. From everything I have read it's really not worth doing without it. My question is can you easily toggle back & forth between custom tune & MPG booster?

It takes a few minutes to load the tune through the Diablosport unit. It's a very easy to follow process. Other than holding your breath each time that it's successful and doesn't brick your ECU:)

My point was that I don’t think you need to. Drive it with some sense when you want mileage, and drive it like you stole it when you want the performance.

Don't bother with the mpg tune, I had zero difference in the mileage. I tried every tune the tuner had and the two custom tunes and if I gained a half of a mpg I was lucky.
