Ok Dave,
Here's what I am going to guess.
Your tuner decided that for some reason, any ICP commanded after 44 MFD was to continue to use the highest values....essentially causing the PCM to run the same ICP at 100 MFD as it does at 44 based on any RPM.
I could see scaling the MFD axis on the ICP map to something higher (like 80 or 100 MFD instead of the stock 70) for better resolution and control, but not lower. Bill has no idea why it was set up that way either.
Bill is actually looking at yours as I type this.
