Check your logs, look at WGDC Actual. If that number is at 100% the entire pull and you are seeing lower than normal boost pressures. chances are you have a boost leak. At Sea Level you should peak in the 22-24 psi range and then the boost should taper down toward right at 14psi at 6000 rpms.15 Apr 2020

What does a supercharger bypass solenoid do?

The bypass valve allows the excess air to be diverted back to the inlet of the supercharger and recirculated. This ensures that the airflow measured by the mass airflow sensor reflects the amount of air actually being consumed by the engine. Using a bypass valve helps improve fuel economy.19 Aug 2010
