Update:
I went back last Saturday. The DA was close to the weekend before ranging from 750 to 1450 but the grains and humidity was double.
The car ran mid to low 10.6's all day. the last run at 1450 DA it ran 10.59. the only other change was skinnies.
I still had cat over temp protection but this time in the middle of 5th gear. I was running pump 94 with vp octanium unleaded instead of the same with 91 prior.
STK was a blip of .5 instead of 3.5 with the 91.
Still wondering what is causing the COT protection.
I did get a recall notice for the cats last fall. Possibly the issue maybe?
I hope they don't have to flash the computer for emissions.
