[Gmecm] 7747 High BLM at idle

My truck has been running okay, but I finally decided to get around to
gathering some more data to fine tune things. I hooked up winALDL and drove
around for a while. As I drive around, all the BLM table values in winALDL
show 124-133 or so - not bad really. The weird thing is that when I pull in
someplace, put it in park and idle it, the idle BLM cell (800/30 in winALDL)
just climbs and climbs up to almost 150. That same cell shows something
like 133 if I look at it before starting to idle.
Any ideas what this could be, or where to even start looking? It's a 7747
for a SBC 350 with automatic, converted from carb.
TIA
