EBC on greddy
 

Would an EBC eliminate the need for the helper spring on a greddy WG?

The helper spring holds it closed better. If the actuator is weak, even with EBC blocking the signal line you will have to use a helper spring to keep it closed otherwise boost will still push it open. That is if your actuator just can't hold it closed.

Makes sense, thanks for the quick reply

i have the HKS evc and it works better than my helper spring ever did.
