Back pressure sensor

Does anybody know if AE measures the back pressure in absolute or gauge pressure? Either way mine is reading 47 psi at idle. . . so I definitely have a problem there! Thoughts?

AE reads absolute for EBP.

Does it change as you drive? Mine starts around 15psi (Atmospheric pressure) and maxes out around 50 at 35psi of boost. Subtracting the atmospheric pressure puts me right around 1:1, which is about where you want to be...

I'm not sure what its doing while driving I never looked. . . maybe I'll check that out today. however 33 PSI gauge pressure at idle isn't a good indicator!
