The injector balance tester is a tool used to turn the injector "ON" for a precise amount of time, thus spraying a measured amount of fuel into the
manifold. This causes a drop in fuel rail pressure that we can record and compare between each injector. All injectors should have the same
amount of pressure drop (+/- 10 kPa). Any injector with a pressure drop that is 10 kPa (or more) greater or less than the average drop of the other
injectors should be considered faulty and replaced.
