Is the bypass mod just disabling the SC bypass valve and if so what does that do? My tuner hooked that valve back up on mine and said it gave the supercharger a chance to cool when off the throttle. IDK?

take the bottom hose off ur bypass actuator..fold it over and put a zip tie around it..
that will check the boost solenoid.
If you get full boost then your boost solenoid is not completely closing..
