Ok that makes sense. What is the most I can run under fuel cut on a standard setup is it 0.8 or 0.9? This one is on my door step it has a ceramic ball bearing rather than metal ball bearing, any difference? Might get him to fit it too http://bit.ly/12XhHzc ^^^ Is that an ok one? Should i Run 0.8 or 0.9 without suffering fuel cut?
