Stall Saver Anybody use it?
On my F-body, my IAC responds well to idle and anything with 0% TPS, but as I let the clutch out, my rpm can drop fast without giving it quite a bit of throttle. Is this something stall saver can help? If you're using it, what are your values?

In HPT go under Idle Airflow, throttle follower Decay(gear) and Delay(gear).
If you lower the decay values the slower your motor will return to idle and possibly prevent stalls, or near stalls. The Delay value controls the delay before it'll pull the motor back to idle speed once you let off the gas.

I recall bringing the "stall saver strategy" RPM up closer to
my idle RPM (my stock tune had all zeroes, I set it to 200RPM
below engine speed near target idle, closer-in at low RPM
(which should not be seen / matter) and 800RPM at higher.
350.00001 400.00001 450.00001 500.00001 600.00001 700.00002 800.00002 800.00002 800.00002 800.00002 800.00002 800.00002
Can't say with any authority, whether it solved anything
but I haven't stalled since doing it (not that it was a
problem before except on very cold mornings where I
had not done a good job with tuning airflow targets).
