Lacking power after injector seals replaced

Hi td5 o3. Disco
Had problems starting. Took garage for injector seals.
They replaced. I picked her up and mass loss of power
Took back they checked over reset injectors to 1 turn
Went and tried still same
Checked hoses. Sensors new harness new maf new turbo modulator
Fuel pressure checked. 4 bar constant
Before they were done. She would pull a house down
No won't pull up hills struggles getting to. 70 mph. No more
Power checked waste gate. Free no stiffness
Running out of thoughts any one got any more cos I ain't

Did they mix up the injectors when re-fitting them?

+1... if they didnt put the injectors back exactly in the order they were before you need to save theyrs codes in the ECU again with a tester

Have the fuel pressure checked - if the fuel pump is dying it may not be strong enough to give the 4 bar of pressure it should run at,and fully purge the system of air since it has been disturbed.They will run with the pump completely dead as long as there is no air in the system,but a slow,tired pump will limit power output - even if it has been able to purge the system enough to get it to run.
Hope this makes sense,festive red wine is taking hold of me as the evening goes on and my feet toast on the woodburner.....

make sure you used genuine land rover injector seals.
made the mistake of using cheap pattern parts and had the same issues you are having.

had genuine ones fitted and it was sorted

Check the fpr as well for leakage, mines down on power needing a new fpr..
