Im looking for a good tuner that will let me go back and forth from fuel mileage and power. . Driving s long distance for work now and trying to get better fuel mileage...i don't really want to get a smaller vehicle since i like my truck too much...it is in the shop right now getting a tune up... new plugs wires oil and filters (oil, fuel, & air)... any suggestions

X2 on a Diablosport and custom tune. I purchased an I2 from Matt along with a custom tune from Hemifever for my 2014 6.4L HEMI.

Oh, there is no shift on the fly tuner options for a gas truck. To switch tunes you'll have to select the tune you want and load it, then return to stock and then load the next tune. It's that way regardless of programmer you pick.
