It's called a high pressure wastegate actuator. I have one also on my PT54. Lowest I can get it is 17lbs of boost. But 18lbs is what it's set for. If you want lower boost get a standard modified actuator for the PT54.
i have an adjustable WG right now in my stock turbo. can that not be used with the 54? i just dont have me alky setup yet so i didnt want to put this thing on knowing i cant get down to 15psi.
It won't line up. It needs a bracket welded on it to relocate the mounting. Nick Macale can do that for too. Tell him to send me $25 for the referral wink
