All Eaton superchargers have an integral bypass by design. The boost bypass, or wastegate is built in, and controlled by an actuator provided by the car manufacturer (pontiac/GM).
The boost control actuator is located on the front of the supercharger. The only thing you'll accomplish by doing this is bypassing the overboost protection in the PCM.
The BCA adjustment has a slight effect, by allowing you to get into boost a tad quicker, but does not increase your total boost.
Try to figure out exactly what you want. That was a little help with terms and definitions.
Please keep all Supercharger, Turbo, NOS, etc posts in Forced Induction. I'll move this one for you.
