Those 'on boost' figures only look good if you KNOW you have exact same fuel delivery to each cylinder. Some would say to go a little further and have a smidge more on 2 and 5 too for extra safety. Have you gone through and checked this? If not then you may be too lean on one or more and your 'accumulated' afr is misleading..... Running very low 12's or mid/high 11's on boost adds safety until you've balanced the fuel to each injector, and checked them for a nice spray pattern. problem is they varnish over time, so without checking you simply won't know
