Yes fitting bigger injectors is better as upping the fuel pressure has other knock on effects to the rest of the cars fuel and electrical systems...
IIRC the Cossie fuel pressure standard setting is 3.5 bar absolute (no vacuum pipe on the reg while you check the reading. Put it back on afterwards though).
