The fuel/air ratio of your engine is completely controlled by the ECU [14 CUX type] and you can't effectively alter it.......its part of the hard/core programming of the ECU, its values derived from various sensors and changing constantly all the time.
Sorry , but YOU can't do it except maybe with a whole lot of specialised equipement including a twin roller dynomometer or a rolling road and the permanent installation of a more sophisticated [expanded memory] "piggy back" ECU.......it ain't just a screw adjustment that you can set "by ear"!
