great idle but dies when pushing clutch in when rolling to a stop Heads and cam, ls6 intake
230/230 cam
6 speed
Runs has a very strong steady idle except when pushing the clutch in and rolling to a stop. Otherwise not a hiccup in the car. Only does it rolling to a stop, start it up and it idles fine.
I attached a copy of the tune. Any help would be greatly appreciated.

Maybe give adding to the throttle cracker a try. Seems that having too much gives you a hanging idle, so a little more should help in your case.
You can also put a higher number in the very top row of your throttle cracker table (lowest RPM row). If you have say 4 in that 400 rpm row all the way across it will dump alot of airflow and keep the engine running when it tries to stall.

Probably need to ADD to the Desired airflow, And subtract some from the throttle cracker after you added to the desired. An example, add 5% to Desired, pull 5% from cracker.
Usually I zero out the throttle cracker table when I am setting up the base tables. Once the base tables are set, then I fix the other adder tables to bring the desired results..
Example, idle is 800, and stays at 800, when you are driving, it remains at 800. However, when moving, I want a target of 1000rpm at various points, then I use the Throttle cracker table to achieve that goal.
