I searched and found 3 threads that discussed this topic, but none ever got to an answer as to where this PID data is derived. We are seeing this timing reduction on our "FrankenTruck" (previous thread on IPW issues) and have turned off all possible torque management/TCS tables we can find.
Ant additional help on what elements in the TCM/BCM/ECM etc. would be much appreciated.
Thank you and have a great Memorial Day Weekend for you all in the States :-)
