Citroen Berlingo losing power

I have a Citroen Berlingo 1.9-litre diesel van (with the XUD engine), and have recently found that it's lacking power. I've had the fuel injector pump and cambelt replaced, and timing looked at, as recommended by my garage.

But although it's better than it was, it is still lacking pulling power. Could this be down to a vacuum leak somewhere, or a dodgy sensor?

Well we would have thought that a diagnostic check has been carried out, before the injector pump was replaced? Has this happened?

Lack of power could be many things.
1.MAF sensor
2.EGR solenoid
3.ECT sensor
4.Air/vacuum leaks
5.CKP sensor
6.Intake air flap control actuator
7.ECU wiring/connections.

Hence the need for a full diagnostic check (with the correct equipment) before just changing each and every item.
