    I guess you missed this recent thread in which somebody measured the WG spring as 38.5 mm:

      well I need something for 500hp+ setup. My boost control can hold the boost with the stock spring. So I will need something stronger to hold arround 2 bar with the help of the bost control.

        All you need to do is change the boost wiring so you use the top and bottom chamber either via a 4 port or 3 port solenoid

          I'm not sure what you mean my 3 port solenoid is connected to the both chambers but the presure which is making is not strong enough to hold 2bar presure. It's making 1.8 peak and then it dropped back to 1.6bar

          However I'm using greddy spec II bost control.
