Right set up my boost gauge from carb base and it is reading when idle vac 20 which i have been told is fine.but took it for a blast up the street and its only going to 0psi i have slightly ajusted the actuator to were i think std boost pressure is roughtly and when i put the foot down i can feel the turbo is kicking in.Any ideas why this gauge is giving me this reading.p.s also try another gauge and is saying the same thing so its not the gauge that is broken.??
