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
