- however, the site has been gone a few years, and I found a printout I had taken of the details - I made this modification to my old Rev2 Turbo. The wiring around the Relay is tricky to work out, but it does work well. I used to use this to keep the car in
'low' boost mode for trackdays.You could also over-ride the ECU and open the VSV to get full boost on cold mornings.
