eah its on 0 when engines off, it drops to 20 when ideling.

will let you know later whats its boosting however i fitted a bleed valve so i might need to make adjustments

69kpa = 10 psi

140 kpa = 5 psi ?

so the lower the kpa the higher the boost?

that right? as my car origanally was set for overboost at 145 kpa and i was hitting that and it dident seem that fast.
