I assume your EGT is roughly 1" from the exhaust port (1.5xport diameter).
1200* is great for cruising. 1500* is fine, 1600* is where **** starts to get ugly.
Your logs looks like you understand the concepts for starters, but you can make it much, much better. Right now your car is basically tuned like an MSM.
my AFR target table looks like this:
You're max boost should be no leaner than 12.0:1. If 8psi were my max, i'd have those target at 11.5 or so. Mine looks different because I'm essentially "ramping-up" to higher boost levels and it doesn't hold 12.0:1 for a long time.
Get that pig-rich **** out of there. Go no leaner than 11.0:1 at your boost levels (more like 11.5:1).
Since you are road tuning, you need to make your fuel table a linear progression on the x and y axis. This makes a huge difference in drive-ability. I hope you have det-cans or at the least knocksense (which sucks for tuning because they human ear > electronics). You'll feel these changes, as well as see them in logs.
Eventually, this will become nerve racking...but when you get drivability nailed, you'll love it. My new "thing" is getting people to drive my car and tell me what they think of the drivability.
