First off, what rpm are you leaving at? When looking at the graph,is it rich while your holding it before stomping the pedal or after you leave? I have gone all the way down to 25 squirters and it doesnt help.I think its the cam.I leave at idle and mine goes into the 9's for a short time then to 12.8 I think it was Tig on here that ground some off the cams to help in this situation.
