It works.I could tell the difference right away! As for the added fuel economy maybe not so much but it will give you an extra punch.

Very pleased with this tuner. Once I completed the update and app download to my phone, it was a very easy interface to use. I particularly like the option for performance, towing, or gas mileage depending upon your driving style. I would recommend this product to other truck owners.
