Coolant thermostat

I bought this thermostat thinking it is the right one for my Ram 2500 with the 5.9L Cummins. After checking back with XDP, I was told that I need this different one, which runs at 180 degrees. So I ordered the one they recommend and installed it. Sure enough, the temperature hovered right around 180 degr. with the "correct" part. However, in researching the topic a bit more I found out that the 5.9L Cummins, or any other diesel for that matter, runs best at around 200 degrees, and has the best fuel efficiency. So I took out the one that was recommended, installed the Mishimoto 190 degree thermostat I had previously ordered and - the temperature is where it was before, right around 190 degrees at light duty driving. I am not sure why they sell the 180 degree part for that application. The old one I took out also said 190 degrees, and I'm happy I kept this one.

My truck wouldn’t warm up, I confirmed the gauge worked and read all the forums, everything pointed to the stat leaking or being stuck open and everyone recommended Cummins OEM, this stat fit perfect and fixed my problem.
