Yes that did come up in our many conversations 
Maybe you guys have some ideas here. I'm still having a small problem with a lean area around 4000-4300 rpm (13.3:1).
Not when I'm powering thru but when I just hold it there. Seems like it just goes back into vacuum far enough to close the PV there. As soon as I touch the throttle she goes rich again which is good. I'm hesitant to fix my rich cruise and WOT until I get this resolved.
The original jetting/PV setup was 82 square and 4.5PV front/rear. The mfr suggested I try 6.5PVs to see if it kept it richer there but it didn't help.
I thinking of going back to the 4.5 PVs with 82 jets in the primaries and plugging the PV and install 90s in the secondary. Just a thought...
