From what I understand the AEM boost safe is based on the fluid level switch input on the system. So not a true fail safe is other things happen.
Here is a link to our failsafe.

The IFS-30C will keep you at WG until meth is flowing. Once meth flow is above set point you can make more boost. With this configuration also protects if a fuse blows or you loose a wire connection on your meth system.
