I don't think anyone has done a back to back dyno test, but the N/A intake strictly from a design standpoint is WAY better than the stock B21FT manifold, and even better than the B230 manifold (longer equal length runners, an actual plenum).

It's an easy modification, and definitely worthwhile if you've still got that craptastic pancake B21FT intake.
