Did you just guess with those parts, or were you guided by a diagnostic result?
If the former, then you really need to get it on diagnostics, and first check for any fault codes and deal with them, then secondly go through live data and see if anything is amiss there.
Sometimes you get a sensor that is reading wrong but within normal parameters so wont show as faulty eg I have seen coolant temp sensors showing engine temp as 60degrees when it is stone cold- similar with air temp.
Look at everything and see if anything stands out

Assuming you don't have a boost leak, maybe the turbo is inefficient.
It could be that the waste gate vanes are slightly stuck & it is loosing initial boost pressure.
You can check the boost on the Delphi, by reading actual boost against the desired figure.
Check that the waste gate rod operates on engine start also.
