If pressure is increased in the system, you end up compressing the steam (a gas, not a liquid). This results in the steam moving slower and needing more water heated at the boiler to create the steam. Low pressure is better than high pressure. In fact, there's some systems that work in negative pressure, called vapor/vacuum systems.

One of the most common boiler faults is low boiler pressure. It is normal for the central heating system to lose pressure over a period of time. If you have bled your radiators recently, pressure could be lost due to that. Or it may be that there is a leak somewhere in your heating system. Sometimes leaks can be so small that they're unnoticeable. It is recommended that you check your boiler
