Hey guys,
I have a TBSS I'm working on with a Truck Norris cam, most other things are stock except for a converter. I'm having an issue with idle. It will idle fine in P/N, but in gear it hunts and feels like it needs more airflow. I have found that I have to really jack up the idle airflow to get the truck to idle at all (~20g/s), but then it wants to push through when stopping as you'd imagine with that much idle airflow. But when I log, I see that it doesn't really even target what I have the idle set to in the table. When I'm coasting to a stop I see it target what I have it set to, but then drops down to about half that once I'm fully stopped. It's strange. I'm sure I'm missing a table somewhere but if you guys could point me in a better direction, I'd appreciate it. Some people say to mess with the throttle scalar, etc. I'm looking for some more pointed advice if possible.
Here's the log and tune file.

In the log at around 2:30 it is hitting the g/s airflow in the table. Then seconds later at around 2:32 it decays to about half. That's when it starts hunting and running poorly.
Thanks all!
