Take any flowing fluid/ gas push it through a orifice and you "will" have 2 different pressures. Increase that orifice size and your pressure differential "will" be less severe make the orifice smaller and that pressure differential increases.
With stock fueling your making x amount of pressure compared to y amount of flow through the holes.
With increased fueling your increasing your pressure but not increasing the size of the holes you will get more flow to a point but your pressure differential will be greater.
I'm seeing that as lost power to a point.
That's looking at it if all combustion occurs in the precup or starts in the precup.
Either the fuel or the air from combustion has to go through those holes. If you increase your fueling and essentially raising your volumetric efficiency I don't see why enlarging the holes a percentage of the percent that you are raising your volumetric efficiency.
