Thermostat Change

Has anyone changed out the thermostat on the SRT8? The cars seem to run hot and a change to 180 thermostat would keep the engines cooler, giving slightly better power. The automakers like to put higher temp. themostats in to get lower emmissions as the engine is hotter. Just wondering opinions on this.

I have a cooler tstat in my car and I'm planning on installing the original back in for now. I'm having Thermostat Rational errors in the PCM. P0128

the logic states that it expect to see a temp change of a given value over a fixed peirod of time for a given condition.
I'm going to put the stock one back in and test it. They are so easy to change.
190 I think
