ABSTRACT:
A method of engine calibration is provided for use with an engine having a plurality of combustion cylinders and a valve train having individual components dedicated to each of the plurality of combustion cylinders. One or more anomalous cylinders are first identified, among the plurality of combustion cylinders, that are operating at a level above or below a common baseline. Changes are then made to the individual components within the valve train, associated with the one or more anomalous cylinders, to provide the one or more anomalous cylinders with individual components having different operative ratings from their respective initial operative ratings so that the anomalous cylinders operate at or closer to a common baseline.
