On furnaces, the gas pressure to the orifice is limited by the gas valve (I
think 3.5 inches WC). The orifice can deliver more or less, depending on gas
valve setting. Or, also can be limited by spiders nest in the orifice, as I
found one time.

As for the OP, calling the gas company for higher pressure isn't likely to
improve the stove performance. With a flame that maintains when other
burners are on, and flame is a good blue. Might be that's how the stove is
supposed to work.

Increased pressure at the meter would make no difference, summer or
winter. Once you have adequate flow, gas is limited by the orifice.
It will not burn any more, winter or summer, in any appliance. A
cubic foot of gas contains a given amount of energy and it will give
it up when burned. Your heater will have a regulator that will keep
it from too much pressure.
