I bought a Tornado 11 and had my Mustang dyno tested both before and after installation. After doing both tests I actually lost two horspower with the Tornado 11 installed. Also, I did not notice any increase in mileage. I am returning this product as it does not do what it says it will do. My suggestion is to not waste your money or your time with this product.
