Iveco 2.8t more power?
Assuming this is the Sofim 8140 engine I believe the higher power versions are common rail so their parts aren't much use to you Are you sure there isn't a computer attached to the pump on this engine? It may be a mechanical pump but computer controlled.
You are in the realms of tuning the pump up and getting more boost from the turbo or fitting a bigger one. Sorry I don't know anything about VE pumps and how easy or hard they are to get more out of.
