your system pressure should never be more than 1 bar (1.5 bar absolute max) when cold - the additional capacity is to allow for expansion when it is running hot and for safety - the system has been designed to operate well WITHIN its limits, not on the edge of its limits. cranking up the pressure that high will only cause the system to lose water via the pressure relief valve or, much worse, through a leak at a weak joint that suddenly isn't up to the additional strains caused by the higher pressure.
and, as john A says, it will have absolutely no effect on the water pressure coming out of your taps anyway. the two are completely separate.
