Pse
 

Just had PSE installed on 200 BOXSTER "S". I,m not installing with vacumes,and relays. Was wondering if by-pass valves or in the opened or closed position? Don't hear much difference in sound?

I did the same thing, but instructed my dealer to leave the valves in the open position.

You need to be specific about this, but shame on them for leaving the valves closed. Totally defeats the purpose!!!

Looks like great fun. Been musing about a GT motor myself or a super charged 3.8.

Warning about the burnt looking engine , I rebuilt a toasted 928 years ago and rebuilding the engine was far less expensiveness than replacing all the burnt peripheral stuff .
