Pyrometer and diesel trucks
I have a 2006 Dodge 2500 with the CTD, since I will be towing my boat (boat and trailer are about 3200 pounds) and the campers about 2600 pounds I was wondering should I install a Pyrometer. Here in t...

My 2008 CTD is stock and I have EGT/Boost/Tranny gauges. I have pulled heavy from coast to coast and border to border and my EGTs have never ever gone over 1250.
One of the things I use the gauges for is to monitor fuel efficiency. The higher the boost, the more fuel that is being burned. Much like the vacuum gauges on the 1966 Chevrolet Impala.
I have also driven coast to coast and the Coquihalla Hwy in BC will easily get your EGT above 1300 if you maintain the speed limit (110 km/h) on the climb through the snow tunnels. It is a long hill. If I slow to 60 mph then I do not get over 1250. I have run the hill in stock, fuel economy and tow tune and will exceed 1300 in all three if I maintain the speed limit. I will also shift the tranny into 4th to lower EGT and fuel consumption. There are also a few passes in Montana, Wyoming and Utah that if you run at the speed limit (75 mph) you will exceed 1250. I usually travel at 60 mph, but now and then I like to see how the truck pulls on different grades:D. The question I have been debating is whether to put on a larger exhaust to lower EGT or just slow down? The down side of a larger exhaust is drone and loss of back pressure for descending hills.
