Yes smurf. Just got back from a road test after pushing in the bottom plug less than 1mm. AFR's on boost at around 5k before plug pushed in was 10.2 now 10.8.
spirited cruise before plug pushed in (less than 1mm) was 13.9 now 14.4. Next move will be to push in plug a little more to lean boost and i bet my cruise AFR goes even leaner. Then it will be time to turn back the bottom allen screw 1/4 turn counter clockwise to prevent further leaning on cruise. I am also plugging the hole in the bottom cap after doing the bottom allen adjust, don't think it should be opened to air. JMHO
