Hey everyone...
I got a hyperboost valve second hand, but was told that the spring may not hold enough boost. Well, unfortunately it didnt after i installed it. I was getting about 17-18psi with the "viggen" bosch valve but now only about 15psi with the new valve. I wouldn't have installed this if i didnt get it for free. But, he gave it to me with 2 springs. One has 3 coils in the center and the other has 4. I installed the one with 4 coils thinking it would be the stronger of the 2. Can anyone tell me how many coils are on your springs? I would really appreciate it. thanks everyone.
