Anyone use a diablo tuner?

I'm looking to get a little more MPG and better throttle response out of my 2017 ram 2500 5.7

Anyone ever use the diable i3 tuner?

I'm not looking for diesel or stock turbo engine responses but thought the diablo might ne worth it

It Aldo seems to be able to change fak controls, at 50 with the plow on she heats up a little, I wonder if the diablo would allow me to turn the fans on sooner ?
