Don't fall for the hype. Stock will give you the best fuel economy. Just keep it tuned up and tires aired up.
The best chip to improve gas mileage is no chip. Inflate tires to proper recommended inflation and drive it like there is a raw egg between your foot and the gas pedal will produce the best fuel mileage. Also driving at the speed limit and not over it will help. Save your money.

SCT tuners makes the best product available. In my opinion. Performance and fuel mileage are both increased. Check their customer reviews.
