Not sure how it flows but I did a gasket match on my stock tb and plenum. I could tell were all the gaskets had been sitting so I smoothed out all the transitions and sanded the whole internals smooth.

Has anyone else tried this or seen dyno numbers or a flow chart on this?

i wish i had my own flow bench setup to try things like this and list improvements if there are any.

i went right for a 75MM TB/plenum combo so i cant really answer your question sorry.

I know getting air flowing in smoothly is as important if not more than getting a lot of air in to keep velocity up. I know with my silverado porting and polishing the stock throttle body seemed to make a difference. But that throttle body could also handle my mods.
