Thanks, that's useful. As of now I don't want to adjust it down. The highest it has gone is 48lbs so far. I just don't want it to be any higher than that.
And now that we have your attention. I'm happy overall with the turbo, it sure would have been nice if the exhaust manifold gaskets had been included with the manifold, and the gasket for the turbo exhaust had been there too. Also would have saved time if the 2 bolts for the turbo had been included, since there are no studs. Had to drive to the store in the middle to get some bolts.
