Lots of folks are replacing injectors, some for more fuel and others simply replacing the worn-out originals.

My question is, must the calibration codes on the new injectors be entered into the ECM, or can the truck run just fine without?

I have both Autoenginuity and AlfaOB but have not been able to find any options to write the codes to the ECM.

Are you folks installing the new injectors and then having the dealership enter the calibration codes or simply not doing it?

Just curious, maybe this information will help others who are thinking about replacing their injectors.
