I have an issue with a hot start stall in an 18 car. It has a PD supercharger, if you breathe on the throttle it continues to run, I've tried all sorts but to no avail. I see the odd random Mustang forum with this issue, any fixes?

Have you added a little idle air?
Tune attached, I have added idle air but will try more. The vehicle is PD supercharged, the file is my own build for a Harrop 2650 based on the stock OS. The car has good readability and power, hot start is the only issue.
Just looked at your log, throttle is open, timing is there, air is flowing, A/F is ok, I'd be looking for an air leak (vacuum)
Anything done to the fuel system?
Try to play with cranking spark, -10 might be way too retarded for power adder.

The spark has well and truly recovered at good rpm prior to the stalling,

This is a different car with the same mods, and tune, it is less pronounced but will stall on hot start if left for 2-4 minutes on the first attempt but will start the second attempt. I'd bee keen to know if anyone can see anything in the log that look different.
Did you ever figure this out? Having the same issue on a harrop 2650 on a 2016 GT, After its hot car refuses to start
In Spark Advance, you can adjust your cranking spark along with CSER spark to advance timing a little more. IATS are 150* causing 7* to be taken away just from the heat soak.
You can try adjusting your Feedforward Control in the ETC tab if throttle body size increased significantly.
