GM calibration lookup
One of the item that comes up on mine is this:calid# 12573568, 12574745 new calibration to correct false setting of dtc p0327
That means Knock Sensor (KS) 1 Circuit
I wonder if that's not a way of saying, "the guy who assembled the car overtorqued the sensor, so let's make it less sensitive"...
