Remember all the theories around the mysterious 8 hp increase between 2012 and 13? Some of this is hype, some of it real. DI doesn't increase power on its own, it needs something to go along with it, like, say, increased compression and/or more aggressive cam timing.
Getting 460 fwhp out of an old coyote is easy. Full exhaust and a good tune will easily net that.
