Does anyone know what the stock max boost should be for this engine??? I have an iiD GAP tool and looking at the live values for the absolute boost pressure while I'm driving I peak at 24 PSI... Seems high. Anyone know?

I don't know what the max boost on this engine but according to Eaton for the R1900 blower, the max pressure is 2.5 bar, which is 36 psi and change. So that sounds about right. Keep in mind the absolute pressure includes atmospheric pressure so 24 psi is 10 psi of boost.

You know that makes more sense... I forgot about that keyword "absolute" an atmosphere is around 14psi, thanks! I talked to a tuning company and they said they see stock boost pressure at about 9.6 psi.
