in my opinion, your idle speed it too low on cold starts, your VE table is WAY WAY screwed up, PE is screwed up, high octane table isnt pretty, over and underspeed could be more aggressive, you can zero out your EGR timing...just to name a few.
Looks like you have way too much idle airflow as well.

Look at the butchery in the HO table.... Also MAF peaks at low 300s now
I'd start with a stock tune and retune from there.

Not to mention the Primary & 2ndary VE don't match...
And they did something I think is dangerous:
They put the Min Spark Advance vs RPM table to 18 degrees across the board. Timing will never drop below 18 degrees because of that. Not good if the engine knocks and it can't pull timing!
