Edelbrock Supercharger Bypass Actuator Valve
 

Hi I've got an Edelbrock E-Force Supercharger on my FR-S, and my Bypass Actuator Valve recently went out. I bought a new one from Edelbrock that will come in tomorrow and I was curious if anyone in the group has replaced it before? And if so I've got a few Questions:
1. How hard is it to replace?
2. Do I need to remove the supercharger or is it possible to replace the valve with it still on?
3. Are there any tips or anything I should be on the lookout for when I replace it?
