It is very easy to use. The directions in the box are very vague. I called superchip for clarification. I drove on a 250 mile trip on the Economy setting and saw no improvement in mileage. I have proceeded to the next setting and hopefully will see better results. It dose seem to have better throttle response. Hopefully mileage will improve.
