Not too bad of a product. Ready to use right out of the box. Tuned the max performance right away, very noticeable boost in power, but only got 10mpg LOL! Watch out on the updates, the 1st one corrupted the tuner, and I had to send it back. But they fixed and returned it for free, and it works great again. Mileage XS tune on 5.4 triton, 3:55 gears, I get 19.2mpg, over the 15mpg original, VERY HAPPY!
