Maddening engine shut down is back

So, I assume stock throttle body. Dirty O2 sensors would cause it - they tend to react too slowly when they get fouled up. However, this isn't likely with the modest mods and presumably "normal" fuel that you use.
I'd keep double checking the spring-loaded flapper door and make sure it closes all the way. This is the most likely culprit. Insofar that this is working, let Torrie send you a new file where he adjusts the Idle Air Control (IAC) settings. When you car is underway (part throttle) the engine gets its air through the throttle body - via the opening of the throttle blades. When you let off of the throttle all of the way (in a turn, for example), the throttle blades are closed and the engine gets the small amount of air needed to sustain an idle through the IAC valve. The IAC valve is controlled directly by the ECU which can target an idle RPM of a pretty wide range.
