1) i would think that installing a boost enhancer and leaving the cv in place would provide enough failsafe to save you.
2) i would also think that installing an electronic boost control unit in place of the cv would also save you.
3) i would also think that going to megasquirt would also save you.

the main reason is because they actively monitor your a/f, boost, knock, spark, etc, etc, etc. and adjust things accordingly.

when things go wrong, the car computer will automatically;
1) retard spark timing
2) decrease boost

if it can't do one or the other (or both!), it further increases the possibility of damage.

granted you can tell when the engine is knocking, when the brakes are locking, when the tires are losing grip, etc. but there's just no way your reflexes can out-perform a computer that's making adjustments 20 times per second.
