My observations:
Seems my HPFP isn't hitting target now, was fine in summer
Coolant temp is 20+ degrees hotter than summer
Timing is a bit more stable across cylinders compared to summer
MAF lb/min is higher compared to summer. So making quite a bit more power. I think 20-50hp more if we assume 1lb/min=10hp
If you're using about the best OCT you can get, I'd give 91OCT map a try, could run same or even more power and more safely.
