I don't remember, not much certainly no more then two turns. 1.5 maybe.
I turned it less becuase I didn't want to have to yank the manifold again if I went to far and it smoked. I may or may not give it another 1/2 a turn or so. It really isn't slugish enough under 3k to make me want to pull the manifold again.
But I did notice my mpg dropped off about 1-1.5. Hmmm.
