I am not quite sure what you are asking, if English is you second language you might want to see if google translate can help.

If I am reading right you think you have low fuel pressure even with a new pump?
What symptoms are causing you to think it is low pressure?
What was the fuel pressure with the old pump vs the new when you measured it?
What size supply and return line are you running?
Are you running an inline filer?
Internal or external pump?

I bought a "bargain" used 3003 throttle body (which includes the throttle body, ECU, 4 injectors, and all the sensors and harness, but no interface or fuel pump), so I've been trying to learn more about them.

I've read up on them a little bit HERE but it's sort of hard to get a handle on. A friend of mine has one on his Charger and likes it now, but had an early ECU failure, and found their tech support to be shaky at best. The original external pumps (that look like a stainless steel coffee can, called the Fuel Command Center) seem to have a bad reputation. The new design external pump (Go Fuel) appears to be a better unit, but I think in-tank is still the best option. I hope you'll let us know if it helps.

Some folks put these on and have no issues, while others struggle to a peak of frustration and finally ditch them (that is supposedly the story with mine).

Was your vehicle running OK before you made the switch to EFI?
