I dont know who that was directed to but Im going to be working on the Tb opening on my manifold. I have the 60mm tb and will also be making the opening into the plenum smoother. But the larger tb wont do much good if the runners cant flow any better, so Ill have to work on those too.
Like areodynamics, you want a good package. Good comparison is a massive spoiler and a massive cam, by themselves they do nothing, paired with other things they do wonders.
