Craig,

my upgraded micro has been hitting 10,800 regularly at our track with a pretty long back straight.   Don’t worry about what the jetting should be.    Follow the signs in the tune.   What you described makes it seem lean.   Read the pipe.   I have found the Evo, while finicky, to be very predictable and it behaves logically the way that you would expect a 2t to tune.   The old carb seemed quite counter intuitive to me relative to past 2t engines I tuned.
