LS engines are more efficient and the cams we are running are not really that aggressive.

I messed with idle screw today and I swear things are getting worse?! Car is idling at 11:1 air fuel and literally canít even idle in a garage with the door wide open. Sooo much fuel at idle. Here are my controller pictures, I have tried adding timing, decreasing map and TPS. Please give me some input.
