What fuel pressure does the 1.8t need? I've got a vvc manifold with the white/beige Injectors if that makes a difference! Not sure if they are standard turbo ones or not.. I have an adjustable reg just need to know what to run.

IIRC 3,5 bar

no, the beige injectors are not original turbo. turbo uses the more modern EV6 injector type. don't have the data at hand but i think the turbo ones deliver a bit more fuel than the beige ones. so maybe you might give a bit more pressure to compensate
