you are running stock timing map with probably a richer AFR ?
What come up in my head would be maybe
1= water temp ?
2=oil temp ?
3= quality of gas used ? (different brand aren't the same as we know it)
4= lean spot a little bit before your peak power ? which should be around 6850 rpm (stock)

Timing map is stock right now. I tried a timing map with numbers ~2 points lower and the car still retards after several runs.

1. Water temp is normal
2. Oil temp gets high. Seems higher than 210F and the car starts pulling timng at WOT.
3. Its 93 octane from Shell, laced with 15% ethanol. There is no better mix around, Chevron is more expensive but likely slightly better.
4. Perhaps. I'll have to comb through a few more logs to see, but in all I'd say timing is ~4 degrees retarded from 4500 rpm all the way up to redline.

I'm so close to getting this oil cooler. Since Summit is within 50 miles, Napa will likely price match.
