if you didn't have a failsafe to automatically switch maps, yes. But you can de-tune any pulley to realistically make it pretty safe, you just wont be making close to the power potential it could be making.
You could be running say 11.8 AFR with 17 degrees of timing on 12psi with 91+WMI, and without WMI when failsafe is triggered just on 91 run 11.2AFR with 13 degrees of timing on the same 12psi. both will be pretty much the same level of safety. but it'll be a solid 20+ whp less on the later.
