that will be something new i've learned
I think it makes sense - Positive Boost is measured in Relative Pressure
Absolute Pressure includes the Relative Pressure Vacuum (negative readings on the Boost Gauge)
My Boost Gauge (reading from the Inlet Manifold next to the MAP sensor) shows Idle around -10 PSI to Full Boost around +12 PSI.
this would give an Absolute Pressure Reading of 22 PSI. ?
