I have a 2018 Ram 3500 6.7 Cummins. Recently I blew an exhaust manifold gasket and warped the manifold. This is my hotshot truck that has 188,000 miles and constantly pulls 19,500 empty and up to 39,500 is the most I have been weighed at. So I installed a pyrometer and I notice I’m constantly sitting around 1200 to 1300 on temps pulling medium weight at 56 I couldn’t hardly get it to back down. Any thoughts and anyone else have some temps to compare to? I really noticed that I can’t hardly pull anything without it getting above the 1250 max I was told.
