.... or do we? The '03-'04 Cobras have this issue. Do we?

Most likely. Those with with a s/c pulley upgrade might like to consider it.

 

Take a look at that kit. Pretty easy to assemble those bits for a lot less money.

I'd look into it a lot more before installing anything like it though. Smells of a little snake oil

 

I am not familur with the 03-04 superchargers installations but for the GT500 I do not see any connections to the bypass valve that will do anything but hold it closed with the throttle open. It opens when the throttle closes. Pretty simple hose connections, not even a computer intervention solenoid in the loop.
