"These designs (he refers to cast manifolds) usually adopt log-style manifolds - good for production but not quite so good for maximum performance. It is necessary to understand that a cast manifold can deliver very good performance, but it is not race car hardware."

You'd think both of these tuners would select the optimum design for their low production custom offerings, no?
