That is going to be your easiest way to increase MPG/Power.

Chips trick your engine's computer into running more lean. I don't like that. And the Fitch thing sounds like snake oil to me. Just my .02. Get a good intake and a good exhaust. Those are engine IMPROVEMENTS, as well as gas saving add-ons.

X3 on the intake & exhaust improvements. The rest sounds like snake oil to me. And those chips are not anything but a way to give your computer false info which makes it lean out the mixture which in turn may burn a hole in a piston or two on a trip.
