Of the included tunes, only 2 do not require premium fuel. A high mileage, and an 87 tune. Of the two, I really can't tell much difference between them. Both do speed up the gear changes and feel a bit more torque, but the fuel economy in the high mileage tune is no better than stock. Fuel economy in the 87 tune is also not much different from stock. A wider selection would be a good upgrade. As to the hardware, it is easy enough to use, if a bit slow. About 15 min to load a tune in 5.7L Hemi
