I bought this tuner primarily to increase my gas mileage. I'm getting a solid 2-4 MPG better on the highway. In town there isn't a noticeable change. The 91 octane performance tune isn't much faster than the economy setting, but both are noticeably better than stock. Overall I would recommend this product.
