Generally speaking, more horsepower means using more gas, not less. While some aftermarket "chips" can increase horsepower I cannot see how one chip can do both. If it was possible the manufactures would do it. They are under so much pressure to improve fuel mileage and horsepower I cannot see why they would not do it if they could. In most cases, the factory "chip" is the best compromise between horsepower, fuel mileage, and dirveability for any given vehicle.
