    No, there isn't a chip that encreases gas mileage and if it was the inventer would be able to retire quickly. There are numerous "hot chips " that increase horsepower. The first drawback is yor vehicle being 4 wheel drive hurts a little on gas mileage. You can get dual exhaust which would help gas mileage improve some and modify your air intake which increases the amount of air the vehicle takes in. The daul exhaust is not very expensive and can of course be done at any mufffler shop. The air intake upgrade can be done also, I would check with the Parts Department at a dealer and see what they carry in air intakes and maybe a performance shop.
