With a 34-row cooler in my '09, I typically peak out at 240F on the track, including at ACS. Before that, I was hitting 300F and experiencing severe limp mode. Obviously the 2012+ model years have improved cooling, but I would still be concerned about hitting 260F+ because you are likely to get some reduction in performance even if it's not full on limp mode.
