LT4 knock module

I replaced mine years ago. I was getting 1-2 degrees of knock retard on a gearshift. The shift felt fine but the car seemed to soften a bit, then pull strong. With the LT4 knock module, the knock retard from false knock was eliminated and the car pulls hard through the gearshift.a cheap mod that works in filtering out false knock from tailpipe rattle, roller rockers and other harmonics that can trigger the sensor.

Another good source of F-Body info is the "Install Guide" database at Project TransAM.
