Getting some great feedback on this and appreciate everyone's comments, I did some more testing yesterday and here are the results:

50/50 DI Water + Dexcool + 160 T-stat
First test: 30min idle time while sitting in the garage with no incoming air (Outside Temp 70F). Fan's pulling in air and pushing over the intake and engine. Temp range after heated up was 186~190F. Average coolant temp @ 188F.

After 30min of idle time I did my last minute Christmas shopping and drove the car around town for +2hr, as you can imagine traffic was horrible but I did get a couple of open stretches and back roads where I could nail down the pedal.

During this time the engine did not exceed 220F and averaged 210F while cruzing. While in traffic at a light the temps would begin to fall under 200F.

Oil temp once engine is heat soaked is around 245F.

Overall the system is maintaining steady temps and is able to suck out the heat from the radiator when needed.

I will keep the current mixture till summer time and see how it holds up in 98F Florida weather.
