NA car, WOT, how lean is OK

That's because also under "More Settings" and then under "Lambda AFR Settings" you have the 8x8 AFR Table for VE Table 1 turned off. Which is fine if you're not using EGO and you're not using this table to tune with Megalogviewer. But you should use Megalogviewer to tune if you're not tuning in real time with someone else driving. So if you do use MLV (use it!) you either have to use the AFR table I've described in Megatune or use the AFR table in MLV itself which looks like this:
The actual numbers for either table you will have to input yourself. Read up on what is a sensible AFR for different load and RPM situations. The one I've posted is on the rich side in boost and biased towards emissions in cruise instead of MPG. Also, reading the Megamanual again will make some of this stuff more clear.

If I had to guess, because he likes his **** to run and not break. Also some engines make more power with richer mixtures than others. My 99 likes 12:1 at no boost. I run 12.5 or 13 and it's slow and will get a high RPM miss. Hell it misses if I idle it leaner than 12.5. But it's butter smooth at 11:1 idle. I dunno why but some motors like fuel. And plus it gives him a safety margin. Some people will take reliability over a possible 5% gain in power, or just dial in an extra pound of boost and run rich and make the same power with less chance for knock or any lean condition.

Is that why I couldn't use VE Analyze a second ago. The only thing really strange about that is I used it a few days ago, and everything went fine. The only difference is I updated to the most recent version of MLV today, I'm about to reinstall from the CD and try it again.
No

#1 make sure you have your most recent MSQ loaded in MLV that you were using when you made your log. #2 Make sure you are using sensible AFR table with the VE analyzer. #3 Reread the Megamanual and search posts here about MLV. There are several. It's kind of pointless to tune if you don't know what's going on.
