I'm my old car (2000 Civic Si, JRSC @ 6psi), I ran the stock throttle body vs a 64mm throttle body back to back on the dyno.

The plots were almost 100% identical.

The engine felt more responsive at tip-in with the larger TB, but it didn't do anything for my WOT power. I sold it and spent the money on a header.
