The present disclosure provides a control strategy for balancing injector-to-injector fueling variations for a combustion engine having multiple combustion chambers (and cylinders), with multiple individually actuated injectors for injecting fuel into the combustion chambers, wherein at least one injector is assigned to each combustion chamber and a common rail supplies fuel to the multiple injectors. The method includes changing the actuation waveform of an injector assigned to a combustion chamber having an exhaust gas temperature deviating by more than the predetermined value from the average exhaust gas temperature, in order to change the amount of fuel injected.
