This was May 5th when the outside air was 83* and was fueled with 93 octane E90, no meth, no nitrous, no chiller. My knock sensors are not desensitized either.

Whats interesting here is that you are pulling no timing out at 140 degrees. I dont know the details of your build but most tuners do pull at least a little by that temp.
