But she flashed up fine and holds 1 bar of boost, but then stopped and left it until I can find out what's safe to run so he can make his way to a tuner and get it set up.
What boost should I set it at and what's the standard boost pressure supposed to be for this Jap crap?

Sounds like a bit of a knob ? Why would he want larger injectors with no way of remapping to suit ?
And are the injectors even the correct fitment ? There are quite a few types.
And as James said, what year of car has he, and what turbo is it ?
And various models run different boost pressures. Once yo start swapping turbos etc, the standard boost control setup will not be correct, so obviously this will need addressed.
And the biggest problem with Subarus, is their owners. Bodging tuning work etc or crap maintenance. Is it any wonder so many suffer damage.
