BCA and BCS

Moved to Forced Induction.

The BCS bypass should only be done as a troubleshooting step. It removes the ability of the PCM to dump boost when necessary. While this is obviously bad for fuel mileage, it can damage your engine at a critical time (WOT, running lean).

The BCA trick rotates the BCA as far as it's bracket will allow in one direction, allowing you to get into boost quicker on WOT. It doesn't add power.

thank you very much!!!
