Mystery table... Before I try to fix the tranny issue I posted about earlier, I've been plagued by a fueling problem. I'm just about to wrap up a decent VE tune, but I can't find something. In my logs, GM.AFR shows the commanded AFR. After tuning the VE with the open loop table at 12.5:1, I returned the open loop table to stock. I set the P/E vs rpm table to roughly 12.7. However, in comparing the commanded AFR to my VSS (MPH), I'm finding the PCM is commanding a 11.7 AFR in 3rd gear. 1st and 2nd follow my tune. But, 3rd is off in lala-land and I can't find the freakin' table to fix this. 
Anyone have any clue where there would be something adjusting the commanded AFR aside from the open loop and p/e vs. rpm tables? I've checked those and the p/e vs. ect along with the p/e vs. iat. Abuse mode has been disabled. Someone please help!
