Thats a picture of my turbo, Its a new Garrett BB T25 turbo. It came w/ an adjustable wastegate and I wanted to know if they raise or lower boost levels. I wanne run a lower settin until i get it tune. thats why im asking. Thanks to all who can help.

 

it adjust how far ur wastegate will open. ur wastegate opens at the desired psi set by the mbc. adjusting this will just vary how quickly itll stop boosting once the wastegate is actuated. it wont adjust ur boost. nice setup tho. u using it on ur hatch? still single cam?
