The following diagnosis might be helpful if the vehicle exhibits the described symptoms in the PI.

The GM Performance Parts Supercharger installation instructions may be incorrect.

The following items may not be used during supercharger installation:

1. The long red wire from the supercharger ECU is not used. This is for additional accessories that may be available in the future.
2. Step #94 of the GM Performance Parts Supercharger Installation Instructions reference installing an external ground. This step does not apply to all supercharger ECU's. Early supercharger ECUs utilized an external ground wire for the ECU as described in Step #94. However, current supercharger ECU's do not have an external ground circuit and therefore this step will not apply to current production supercharger ECUs.
3. The small, white, 6 pin connector will not be used. The 6 pin connector is used for flash code diagnosis by connecting a test light lead into Pin 4 of the connector.

Note: GM Performance Parts is currently reviewing potential instruction updates.

Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed. If these steps do not resolve the condition, please contact GM TAC for further diagnostic assistance.
