I am having a similar problem. The car fires up great when cold but quickly goes lean as soon as there it warms up or if it has run for a few seconds. I'm SD only at the moment and not making any progress with the issue.
What version software are you using? I have 2.22.3152.18236 and can't open your tune.

I can't say I agree with your fueling or spark tables. Perhaps try forcing open loop speed density for the meantime while you dial in your fueling. Start with a 6.0L tune for the VE table since that's the closest engine to your displacement, then go from there. Your VE table is horrendous.
