Fueling on a low boost turbo

[jones91]

Hi I am having a low boost turbo conversion (5-6 psi) on a mk2 vts, I currently have an adjustable fuel pressure regulator fitted, but will I need to up the Fueling system e.g bigger injectors and fuel pump and what would be the best car to take the parts off, or would it be ok to just wind the fuel pressure up a bit?

Any help appreciated thanks
