External fuel pump recommendation

I've been through the forums multiple times, but probably more confused than when I started. I have recently bought a fully built R33 GTST. Basic rundown, fully forged motor, head work, cams, Plazmaman top half intake, Sinco twin scroll manifold, Holset HRC40RS turbo, full 3.5" exhaust, Link G4 etc. Fuel system currently is an unknown intank (possibly stock), to a surge tank in boot with a single Bosch 044 external (run off relays etc). Current tune was 403rwkw, on 20psi running 98, but we were maxing injectors - plenty of headroom everywhere else. I'm going to upgrade to 1000cc injectors, but I'm aware that for anymore power, one external pump is not going to cut it. The lines look to have been changed to braided through to the fuel rail, I'm guessing from a quick glance they are -8, and I'd prefer for simplicity (and because the car is already engineered for the fuel system) to stick with a single external pump rather than going the dual Bosch route. Has anyone used a single Fuelab, Aeromotive or Pierburg external pump over this power level? I'm looking to max out the turbo at around 470rwkw, and car is mostly street driven with the odd track cruise and casual roll race day here and there, so most of the time it's turned down to around 360rwkw, only turned up at the track. Any first hand experience would be really appreciated! Looking at other posts, I know a lot have in-tank dual pumps, or dual Bosch 044 setups, but again I'd rather just upgrade existing components so I don't need to re-certify for a major change.
