In a lot of cases it not the EGR but the fuel. Pressure test your fuel, and check your fuel filter.
It sure would be nice to understand what the poster is asking.
Because a DIY'er reads insufficient flow from EGR, that must be the issue, and now he has changed some very expensive parts and does not know why it didn't fix the issue. But that's what it said, LOL
How does one pressure test the fuel ?
With a fuel pressure tester, which includes a hose, fuel rail connector and fuel pressure gauge.
