The Anti stall dip you had before does work. (this is the cool thing with this distributor its not a recurved but programmable)
I am using it and with this, mine idles even when it goes to 500 rpm.
With 7° mine would never run.
Try once at your first curve to take off point 4 and point 5, set point 6 to 3000rpm.
I will try soon to use the manifold vacuum and programm it above 1500rpm to kick in.
