Let me tell you .. The FV in my Porsche was disconected in the past by a nasty mechanic and let me tell you , It was a nigthmare man.
Like Jim W . says don't disconect the FV, you wil l have a hell of a time. If you want to experience the behaivior of a 3.0 without the FV just disconect the electrical lead that goes to the FV and run the car. You'll see.Man
