Do NOT mess with the bypass valve'* ability to dump boost on a street driven car. Start a new topic if you'd like to know why. That would be best in the Forced Induction section of the Forum.
The BCA and BCS are not the limiting factors in your boost level. The pulley alone is. It'* an on-off switch assuming everything is working properly. You either get it all, or none, based on the position of the BCA. Modifying the BCA and BCS will not get you any more boost.
This topic is 5 years old. Please don't dig up the oldies. Start a NEW topic. In this particular case, we know alot more than we did 5 years ago.
