idle is very rich need help tuneing I have EFIlive and LS1 edit software. i have my MAF tables tuned good and my WOT is as good as i can get it with stock O2's. I just have no idea where to start or what tables to adjust to get it to lean out the idle. Any help would be great thanks!

I would start with the LTerms at idle and first make sure those are within +10/-10.
There is also a table in edit called open loop a/f.....something like that. It controls the a/f of your car for about a minute after you start it on a cold start. Reducing this table at the right MAP/temp will pull some fuel out of idle on initial start-up.
You could also try reducing the VE table values in edit for the 400,800,1200 columns. If you reduce this column too much the car will hesitate when you start rolling.
