      The 4 port is the one that really makes a difference then as when the valve is energised it reverses the connections and the turbo pressure slams the WG shut. Yes?

                  Hey Bo
                  Can you let me have a 3 port plug and play? How much to ship to Oz? Have you sorted km/h dials and chrome rings yet? Let me know how to pay you...
                  Cheers

                      I can't imagine that any mapping tweaks are needed to run after Market 3-port N75... Unless there is a big difference in latency. Both are duty cycle controlled devices... Set them both up for 50% and they should both be open and closed half of the time.

                      The aftermarket ones are supposed to be more robust than oem - especially on big boost. It would take some time to test latency of both devices - by which I mean the time taken for it to respond to the open and close signals

                      biggest gains wi come from 4port operation where n75 actively closes the wg - this mods definitely requires anew turbo map though... Been wanting go experiment with that for a while ;-)

                        Do I need boostcontrol to have this installed?

                            Bo, you got any P'n'P ones left? I might also need your bank details as i think I decided I had given you enough money already and deleted you from my Bank Transfers list

                              Nope, 3 port is plug and play.
