I listened to Wes Duenkel on Kenny Brown's Cars and Coffee this morning. Wes wrote a book about modifying 2011-2014 S197 Mustangs with the coyote motor. I have a 2009 GT with a 4.6 3V. Already have installed lots of chassis and suspension mods. Is it worth $33 for Duenkel's book, if I need no advice on chassis/suspension tweaks and the book doesn't speak to 4.6L V8s?
