Default Can I use a different WG Actuator on stock TD04

I have a 2006 WRX that is currently stage 2 with a cobb catless DP and STI catback. I have adjusted the stock WG about 1 turn shorter but the WG flutter is still pretty bad I was wondering if could upgrade the actuator to a stronger one so that it can control boost better and stop the flutter?

Let me know what everyone thinks.

Thanks
Dan

Um...it's normal to have wastegate flutter?
You can't prevent it, someone will post a link to the thread soon (from the looks of this forum)

Typically, enthusiasts will turn it until they've reached their "target boost" level.

I've heard other members who have turned it too far and the boost gauge will fluctuate, they back it off a turn and no other issues.

Or you could adjust your map to use the wastegate better.
