A programmer, such as the Edge CTS3 # EP39YR will give you a slight increase in your 2015 GMC Sierra 1500's mpg. Typically, the mileage improvement is marginal, usually around 1-2 mpg. The actual increase you see will depend on several factors, such as the overall condition of the vehicle's drivetrain, driving style and the environmental conditions in which the vehicle is being operated. There really isn't a product on the market designed to drastically increase a vehicle's mpg.

This product is not CARB approved, so it should not be used on vehicles registered in California. If you click the provided link, you can see an FAQ article on performance tuners.
