I've got a strange problem with the Suburban in my signature(or at least seems strange to me, but maybe is normal)where the 800/30 cell(I think the 800/40 does too) runs down to 108blm when in park. This same cell when in gear however is tuned to, and registers when logging to be around 128. I've gotten everything dialed in, but these cells at idle in park. Biggest reason I am concerned is that I've got an emissions test coming up in early May, and here they do a parked idle, and a parked 1200 rpm test, and I'd prefer to have the fueling where it should be. So is this something that is normal, and either way, is there something I can tune to fix this?
