Should explain it starts at 13 and works its way down to 12 as boost increases, it sits in the very low 12's on full boost.

It does richen up instantly

Pretty much what it's doing, but it never used to do it. I'm not so bothered by the lean off throttle reading as this sounds normal from the research I've done, more the jerkiness and unusually excessive popping.
I'm slowly adding the tools and components to go OFAM. Maybe I'll stick it on my Christmas list and my problem will go away.
