Supercharger replaced ET slower
I had the supercharger replaced under warranty. My ET dropped .3 to .4
Car performs good. Any ideas on why the ET went down so far.

bypass valve not properly adjusted is my guess. It is most likely bleeding boost/airflow through that valve.

Just because the super charger was replaced doesn't mean that's what caused the slower ET's. Was the slower ET's on the same track? Was the temperature and barometric pressure the same? Was your traction the same? How did your 60''s compare?

Just give the new Sc sometime to start performing .... & btw 0.3 / 0.4 is a very small difference that could be caused by many variables like temps , tires , etc...

Or the dealership didn't remove the plastic cover off the supercharger exit when they installed it and its blocking the intercooler like I seen in another thread.
