W124 1992 602 - Boost values correct ?

[Chris_]

Hello,

on a 1992 300D 2.5T - I am achieving the following max boost readings under load using a quality shop gauge - I believe that these values may be low but I am not sure.

@< 2000 RPM = 2 PSI
@ 2000 Rpm = 7 PSI
@ 2500 Rpm = 12 PSI
@ 3100 Rpm = 14 PSI

I am using the modded wastegate setup such that it is mechanicaly controlled via pressure right off the intake manifold.

Thank you
