just wanted to give you two a great big atta boy!! since I had Bill live tune my 550 my mileage has gone up tremendously. The best I ever got before was 13.1. yearly average 12.2. the first tank after tuning was 11.9, but that was with alot of stupid stop and go in Atlanta and towing the trailer. THIS LAST TANK I GOT 14.3 ! Never ever have I gotten that kinda mileage on this big ol beast. I still love the way it runs and will continue to be your #1 cheerleader.
