If you're interested, I have brought in a couple, I will be installing one on my vehicle to document the ease of installation.

Well considering my car wouldn't require do to the mod based on its mods I doubt whether I will see any benefit.
I need to explore a bigger turbo soon....hmmm

Umlungu, you can use my car as a demo :)

Need to get my fuel system sorted.

What difference is there in fuel delivery / pressure between this pump and the RS fuel pump?

I have an open box of 550cc injectors I have thought of putting in my car but its the added issues with the software that go along with that...
The Fuel Pumps are here, I am just going to document the ease of installation for the big turbo guys.
I intend on going for a bigger turbo in the near future and thats when the injectors will slot in.

Well apparently the OEM RS pump isn't the highest flowing pump around, so either way you look at it this pump will be a massive upgrade.
If you have a big set of fuel injectors you will have a large flow demand from the pump, and if you're utilizing as much as you're flowing you will experience a massive pressure drop when the injectors open up!
Ideally you want to keep the pressure constant with no drop in boost as lower pressures means less fuel atomization by the injectors.
The guys that experiment with Ethanol mixes will know this well.

Flow should be better yes. But to rephrase my response to OP is that the pump don't regulate pressure so the max pressure you will get will be exactly the same...

So here's how I deduce my car's components working / performance order, at 5,000 revs on 1.7bar boost the AFR is sitting at 11,5. So my fuel pump is delivering what it should. Is that correct Pat?

I will throw a spanner in the works here:
As your pressure drops your fuel atomizes less, so your AFR becomes richer because the motor burns less efficiently due to time (from High RPM) and the less efficient coverage of flame front across the surface area due to an altered flame front speed from the increased density of Fuel molecules.

11.5 in my opinion sounds rich, I would have expected to see 12's in boost but you are most probably having to run rich to smother pre-ignition in the cylinders with the fuels latent heat of evaporation.
