I have a 99 Z28 with a Power glide trans, heads and cam car. Its pulling timing and the PID I found it with is "Total Torque Control Spark Retard" How do I zero that out or where is that coming from?

How much timing is it pulling? It sounds like a traction control parameter. Check the values in either B1902 or B6605. With a Powerglide all of those tables should be disabled, but double check.
Can you post a log?
