Really? I have a ZZP actuator on my V3. They recommended it a year and a half ago. I just checked there website and they removed that recommendation since I bought mine.Has a better firmer spring then stock turbo but ZZP doesn't recommend running ZZP actuator on their v3 turbos just something to keep in mind! Not really a HP gain mod just holds better boost for now with this trash turbo lol cant wait to get rid of it
