The ones you get from JWT (and I believe from Z1 too) on the 700BB are threaded (adjustable). The only reason you would need to change them is if you want to attempt really high boost in which case you would want an actuator with a stiffer spring (and thus a higher minimum base boost) like the forge actuator. I almost swapped mine out for forge actuators but decided it might be tough to push mine much past the low 20's due to the flow improvements we made with my engine. I guess sometime next year I'll see how wise of a move that was.
