As you guys are noticing, what I really did notice wasn't the differences in peak numbers, but consistency of the manifold. Hell, these all are pretty close max flow. To get the engine running optimumly with a "faulty" manifold, you would have to have the ability to tune fuel delivery per cylinder.

Beyond that, an engine is going to run best, and behave the best if all 4 cylinders are making the same amount of power. If you have one runner that has 10% less air, you wold have reduce the fuel accordingly. But in doing this, that cylinder will make less power because it is consuming less air/fuel mixture.
