removing some fuel.

In my speed density ecm, Since I am having trouble with my aldl port and cannot datalog yet, I know I am running quite rich still, In the VE tables, Do I raise or lower the numbers accordingly to make it run leaner? I need to do something until I can run the scanner to see where I am at.

Thanks, That's what I needed to here. I did lower the numbers ten points all across, But on my Drive, I could smell something, And maybe a lack of power? But Look, I'm running 42# injectors on my combo. Maybe setting the injector rate at 42 was good enough and the computer + o2 sensor can compensate?

I would datalog but I can't.

Just lowering the VE tables will not work unless you are in Open Loop all the time.
CL BLM will drive the fuel right back to rich where the o2 constants indicate.
Adjusting the o2 constants is what you'll need.
Might try the R/L Offset vs Coolant Temp table at L84F6 as a crutch until you can fix it right.
Will subtract from all the 3 of the o2 parameter tables when not at idle.
Idle has its own settings.
Go down in 25 mv steps (not counts) to a max of 150 change and see if it improves. Don't go too far and watch your temps.
