I know Banks and others claim more mpgs, but I have never talked to anyone that have actually seen more mpgs. My expierence is better performance, cooler running engine, but the same mpgs. BTW the newer Fords and Chevys don't get the same increase in performance as the older 460s and 454's do. So as others have said I would not buy it for improved mileage nor expect it to pay itself off.
