What the Stage 2 label indicates
In automotive tuning, Stage 2 generally describes a modified calibration rather than a stock file. The label does not identify which engine control settings were changed or what hardware the tune expects. It should not be taken as evidence of a specific power increase or feature.
An engine control module normally uses calibration data to manage functions such as fuel delivery, ignition timing and emissions controls. Those are general responsibilities of the controller, not confirmed changes in 89663-60J20_Stage2.bin.
