Tuning without a WB -
RAFIG/PN and idle -

I still haven't had a chance to look at your log. But unless idle is giving you a lot of shit, you probably won't have to do most of what's in my tutorial. The RAFIG/PN process is always good to do no matter what though.
Some things to keep in mind:
Assuming this build is waiting on a turbo, it's probably low compression, right? If that's the case, it's not going to make the same power as a normal N/A block. Pretty much a given. Normal N/A LS-based motors usually run ~27* of timing with aftermarket head/cam setups. At least, that's usually a good average. Some take less, some take more. How you're pre-turbo setup will run - IDK. Regardless, I have to ask - why are you spending so much effort to get it to run balls out before the turbo is installed? If you're working on idle or part throttle drive-ability, I get it. Otherwise, I'm at a loss here...
