Puma injector service?

[n plus one]

Anyone had a specialist diesel centre service/calibrate the injectors on their Puma?

Not experiencing any issues, just thinking about whether this is something I should look at getting done now that: a) I'm doing my own servicing; b) the truck's North of 100kms; and c) the truck only gets used for big trips/remote area work.

Any thoughts/experiences/reflections?

Should be able to have the injector feedback values read by dealer or injection shop. That should evaluate condition, then act from there if necessary.
