is the injection pump calibtates for a specific car? or is it just calibrated for it's own need?

Basically what I'm asking is...can I remove an IP from a good running engine and install it on another engine without recalibrating the pump?

Both are 617 turbos.

I have a running parts car and was curious about this. If say I wanted to trouble shoot a problem by swapping parts, can I just swap IPs and see what happens?
