Boost and Auto VE What am I doing wrong? I'm already lean in boost and it looks like it's trying to take away more fuel. My AFR @ 135 kPa= or - is 12.70-15.08 which gives it an average of 13.8.

I'm having a hard time seeing your map screen shot. One thing I could tell, what that you have one map to cover from 15-215 kPa. It will probably help you to split the VE table into two maps corresponding to your calibration. IIRC, one map will be identical to your VE table (15-105 kPa) and the other to your boost map (105 - 215 kpa).
From the chart view, you're commanding 14.xx AFR under the highlighted region. You should be commanding much richer than that.

TAQuickness id dead on right.
Plus which cos are you using? COS5 has a table that lets you set the target AFR plus you need to set PE to activate at 40kPa and set the rpm vs PE table to 11.5 : 1 just for starters....can lean it up later.
