Your fans need to be reset.
Well I don’t think I’m harming anything by not adjusting the fans, it’s just not optimized like it could be. When I’m in track mode at the strip and the chiller is running and I have the cooling fans turned on it does run right at 185 ;)

I think it’s pretty cool that these cars can do that stock. I remember pulling a fuse and bridging the connection with a hot wire to force the fans on with my 300 SRT8 back in 2007 to cool it down between runs. Also had to ice pack the aluminum intake runners.

This redeye you just put it in track mode and it kicks ass. One time I made 7 passes in a row, in like 15-20 minutes. Every temperature on the car held steady and was still in the optimal operating range. My friend in his Z06 only got 4 or 5 passes before it got too hot.

Just a couple thoughts, I do run a 180-185 or whatever without a tune, it does keep the car cooler at almost all times, but will still spike to 220 water temps in traffic idling and such and can take a bit to drop back down to around 200 until you are moving and get some air flow.

Also all 180s do not behave the same. This spring I ran a Mishimoto, and that one did open in the upper 170s and then settled to around 179-180. The Jet 10183 which is believe is also the same as the Motorad 4128 will not open until 185-188, then will hope about 185 until you are in traffic and such. The Mishimoto gave me a code right away. I do not get a code with the Jet/Motorad on the stock tune. That abut extra 10 degrees before initial open seems to make enough of a difference.

One last thought, I usually swap the stock 203 back in for the winter season, and my car runs at almost the same coolant temps in the winter with the 203 as it does in the summer with the 185
Oh!!! Now my old mind remembers! That is why I remember changing the old car (daily driver) many times! There is winter. I was damn quick last night with the Hellcat, it is very easy to wrench on compared with a 6.1L in the thermostat area anyway. That sucker will never need to see winter.

Any thoughts about removing the 220 degree thermostat all together? My thoughts are that here in Florida we never get cold enough temperatures that warrants it.
This is how I felt after reading this...

The GTO had a tech setting for the cluster that fed you the actual readings, not the idiot light range stuff. After tune, SC, etc... she ran 180 to 185 all the time. Only w rare excursions from there range.

Maybe, since the humidity tends to be quite high in Florida, both the thermostat and coolant can be eliminated.

After all, the ambient temperature there isn't all that much lower than what the engine was designed to run at.

I have never seen 200 with mine. My 180 runs at 185 and when it gets to 195 it opens and goes back down
Mind acts this same way, maybe it’s the tuner not the Tstat??🤔
