Technically, the stock DME is only reading what the PROcede transmits to it. Only the PROcede truly reads the TMAP pressure signal.
I too am dumbfounded as to the discrepancy. If there is enough range with the TMAP sensor, then there must be a physical reason. I am wondering if there is a phase change in the VANOS system which could cause a reversion in the intake manifold under these specific conditions. This may not be seen outside of the manifold...
