Not sure why you quoted his question to me. The test he was asking about, and the one you appear to be asking about now, are of the same motor from bottom to top, with the exception of a swap from a 75mm TB to a 90mm TB on the same TFS Box-R upper manifold. The TB swap resulted in 14 extra hp below 6000 rpm.
So it was the exact same upper intake (not removed) and it was just a TB swap with a port match opening? I would enjoy reading this article.
