The show said they just put a BD TC in and the BD valve kit along with blue printing the valve body. They changed an exhaust manifold, larger turbo (not sure if it's the supermax),Dominator program I think and I can't remember what else if there was anything.
It was someone's personal truck who wanted this stuff added.
