Since you have no leaks, code 55, and everything is checking out within spec, I would start by bypassing the AFC. I've seen it cause strange readings. It might be good to re-initialize. Then, if that is not helpful, start replacing parts w/ known good parts that impact A/F: MAS or MASs FPR - unless you have a guage that shows it rises properly Epromm if you have the stock one- turn down boost, go back to single pop Whatever you do, do one thing at a time to isolate the problem.
