For the price of less than half of the name brand tuners this programmer gained me 1.5 to 2 mile per gallon on average in my early 2000s 5.3 Chevy. also ordered two more for other Chevys I have and Report the same gains with the same engine. What's not to love. Only knock I have is tuner can be laggy and not completely load program at times causing a need to reset and startover

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
