Boost Gauge Not Reading Correctly?? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Well I recently finished my Sr swap. I installed my boost gauge and manual controller. The gauge only reads about -20ish and only 5 psi when i'm in boost. I kept upping the boost but nothing changes. I'm pretty sure the boost is still turning up because it feels slightly faster every quarter turn. I want to run a safe level of boost and get an accurate reading so this is quite frustrating.

^^Yup. Boost gauge needs to be hooked up to the intake mani to read proper vacuum & boost. Don't tee it into your FPR line if you find yourself having to tee it.

It is tee'd into the a vacuum line running to the throttle body and that is probably my issue. Does anyone have a picture of where on the intake manifold they hooked it to? That would be greatly appreciated.
