    I think it will probably make your gas mileage worse, stay away from those things, they are basically scams.

    More power equals more fuel Performance Chips would not help gas mileage if they did Nissan Factory would have them already. 2006 4×4 Xterra weighs a lot and is not aerodynamic. Fuel mileage would improve with free flowing exhaust and light application of the right foot.
