Hey all. So my recent 90k service on my 991.1 turned up a bad COV valve for the sound symposer. This means I need to either replace the valve or delete the symposer (disconnect and plug) all together. Another option for a delete could be an upgrade to an aFe high flow airbox.
Looking to see what others think or have experience with. For reference, my 991.1 is a base with PSE.
