Rune,

I'd say you're whole combo : capacity, compression, camshaft, choke, emulsion tube, main, and air corrector produces a really strong signal at the booster and your e-tube/choke combo can get away with less accelerator pump volume/duration.

Ideally, this is what we would all like to be chasing, to have a carb that could respond well enough to not need accelerator pumps.

Alas, this will never happen due to the difference in mass between air and fuel.

I'd be fitting 35 bypasses as a start.
If you have the later IDFs with the adjustment nut on the acc pump rod, wind the nuts out progressively to reduce the volume.

35 is the smallest offered by Weber, you can then drill them out to 50 then 60 etc if needed.
