Alan, it is unlikely that if you find a stock 930 to drive that it will also be in a perfect state of "tweekedness" or tune. CIS has a lot of room within the tolerances were it will run acceptable but is far from optimal.
Every little bit of tweeking you do will be significant in the response you feel from the engine.

Goran, can you interpret that graph? I read those so infrequently that I have never gained a full understanding of how those islands affect operation and specific engine characteristics.
