If that were the case you can lower the effective area in the idle airflow section down to something like .5 smaller than it is and see if it has any affect. That is your percent max and percent max brake settings. I'm still coming back to a mechanical fuel problem. You might even want to dump in a large dose of lubricant like marvel or lucas and run it through the tank just to see if the problem starts to subside. If it does then look into injectors some more. I assume the tank was thoroughly cleaned by hand?
Hopefully if the injector data is wrong, that's all it is, but I would still run some cleaner/lube...
