My car is boost is about 9 psi and ive read that it should have about 14 psi . All hooses are Ok, vacuum hooses, pierburg connected but cant feel any overboost also. Any ideas of what`s the problem? faulty pierburg?
Any sugestions?

Also, ive been trying to make the waterspray work, the relay is on its place, ive tried joining the cables of the pressure sensor, and i cant hear the relay clicking. I think that maybe there is another relay, or the relay im checking is not the correct.
Ive tried to conect the electric pumps directly to 12v and they work great.

heeeellpppppp !!


thanks
