I seriously wonder if you could log the pressures the sensors see with VAGCOM /VCDS software and a cable.... I am almost certain that you can do so.... Seriously, my buddy was doing so on my passat about a week ago, while I was driving, had it hooked up to the OBD II port, I know for fact we saw 2500 millebars pressure, absolute, requested, and very close, 2450, actual, delivered at 1700 rpms with the VNT turbo on my 2012 passat... that's 22 to 23 pounds of boost, which is insane, to the edge of stalling the turbocharger to the point of causing fluttering and causing what is known as turbo surge.
Don't log at the OBD.
That is third hand, garbage data. Manipulated, massaged.
Use an inductive probe to see what the sensor really sees.
The only way to truth in this business is to see the raw data.
THEN compare it to the OBDII reported data.
They will be different.
If you can figure out who the supplier for the sensor is, another key piece of data is the specs for the sensor.
