Short on fuelling - what next?

[andysmee]

Some advice please.
 
My FD is relatively stock and running at 0.8 bar at about 280 rwhp but it is running very high injector duty cycle which is stopping me taking the boost up and getting better intercooler and things sorted out as I wouldn\'t be able to add more fuel.
 
Question is, out of the following, which do I need to do next in order to progress things:
 
1. Injectors - bigger primaries, probably 850s
2. Fuel pressure regulator (I happen to have one waiting)
3. Fuel pump
 
Ta, muchly :cheers

Fuel pump first out of them all and would get it changed before any major things like bigger primaries, the rest will follow.

Do you already have bigger secondaries?

[andysmee]

no, secondaries will be stock on 850 IIRC

I went with bigger secondaries, rail, adj fpr and bigger pump.
