These questions are not rhetorical please chime in if you are following in real time.

Seems normal as the PCM is monitoring and adjusting fuel/spark/throttle position in real time to maintain required RPM.
BTW, I cant thank you enough for this thread. I have stumbled around for years without making any progress on my HP tuners (other than able to get stock engine to run stand alone). Suddenly with this thread I am starting to understand how it all works, and spending more time in the chevelle than I have in a long time.
