Ford Copperhead Stalling Issue

Have a 2011 Coyote with a Ford Performance harness/computer in a 1967 Mustang.

Adjusted the tune, the car drives great for the most part.

Last issue we have is that if you are driving and push the clutch from higher RPM and roll to a stop the car stalls.
My experience is all GM tuning.. I don't see anything that is similar to a "throttle follower" table.

If you are careful and slowly slow it down to about 1000 rpm and come to stop it doesn't stall.
I adjusted the Idle Airflow - Drive table, owner says the throttle response feels crisper and the situation might be marginally better but I don't think I am hitting the right table.

Any input is appreciated.
Thanks

Does the speedometer work? If not then that is your problem.

We would probably need to see a log and tune as well...

Great question. Didnt cross my mind to log and check it. Will check and report back. Thank you!

check the check vavles on the brake boost line could be something missing had it happen before

Car doesn't have power brakes but we will look it over for something related.
Thanks for the input.

you may need to adjust your decel from torque based to dashpot

The idle airflow - drive table (44239) is for automatic cars while in the drive gear. For manual cars, you adjust the the idle airflow - P/N (44242).

Odds are, that's not your problem and I would put them back to stock for troubleshooting.

I suspect this is a torque table problem.
