B4512 - anyone know why the HSV GTS has B4512 correction values that are 0.75 g/sec LESS, at deltas of .05 .06 and .07, for the RPM Decreasing table.
2001 Z06, and most other tuns I've checked, the values are equal for RPM Increasing and Decreasing.
See comparison tables below.
Why the difference in Learned Correction AirFlow?

Does the GTS have a much larger cam?? Assuming a greater rate of change in idle airflow. With a bigger cam, does this smooth the rate of change as compared to the larger RPM Increasing values??

Is the GTS a 90mm TB??

Thanks in advance
