Well the coolant may have been more water than coolant before I flushed it today. When we did the break in we only used water in the engine (just in case any leaks). Then when i started fine tuning the trans I didnt do a perfect 50/50 split of coolant/water ratio. So today I fixed that.
It was also only 90 degrees outside tonight while driving, I kept my speeds up, and didn't stop as much. So probably a conglomerate of things contributing to having a cooler engine tonight.
