There are no throttle cracker/follower tables in NBS trucks.

Nope, not a straight equivalent at least, most just use the airflow tables to adjust the idle recovery currently. You could also probably use the minimum idle speed desired table since it can be set via mph rather than ECT. I know HP Tuners has this table under engine-idle rpm.

The throttle cracker table is essentially rolled up into the desired airflow table as the Minimum Idle Airflow table. Columns are gears 1-6, N, R, P and row value is RPM from 200-8000.

my truck does the same thing every time I reflash the pcm... If i drive it around town for a couple of hours it learns to control the idle all by its self. If I move the complete idle airflow table up about 5% it seems to help a little, at least then it doesn't die. How long has this been going on?
