Looks like you are still running closed loop.

Stock injectors?
I dont have efilive on this pc either to look at your tune file, but if you have larger than stock injectors, you may need to load the cax file for B9021 minimum transient pulsewidth.

Can you post up the stock tune file as well?
I will only be able to have a look tonight when I get home to see what you have done so far. But at a guess you will need to drop at least 20% from the idle areas in the VE table. A cam that size will need a reported wideband AFR of around 15.8:1 and at least 26 deg base spark IMO.
Also make sure you have bumped up the idle speed to around 1000rpm for starters & added 2G/sec to the desired airflow table.
