Attention:Those values are stamped on the injectors during the manufacturing process. The injectors contain a piezo electric element. Due to the differences in conductivity of the piezo crystals, each injector has a slightly different tolerances when it is manufactured. All injectors go through a testing process in the factory and their measured tolerances are stamped onto their casings. When you replace injectors, you simply tell the ECU what are those tolerances.
