It's OK for there to be some difference in fuel flow, but yours seems excessive, especially the huge difference in leaning capabilities between the engines. These fuel injection engines need to be calibrated using special guages and following the manufacturer's recommendations. For those in northern latitudes (not you and me), I've heard that the calibration ought to be done twice a year, for cold and hot weather. Although I believe an A&P can do it, provided he/she has the specified guages and the procedure, I take it to a specialist who does it often, to make sure it's done right.
