High EGT's

I am new to the diesel motor crowd. I just bought a 2009 F350 6.4L with 44K miles. My husband put a cold air intake and a tuner chip on the truck for me to monitor while I am towing in the mountains. He has a 2002 GMC 4500. I have noticed my EGT's (staying in stock mode without towing) stay around 350 at an idle, and it doesn't take anything to push them up into the 900's. His GMC idles under 200 and I really have to have my foot in it to get above 800. I know nothing about motors

, are my EGT readings normal for this type of truck?

Normal. I'd be more concerned if you went above 1100, You have to remember you have a twin turbo set up, and chances are your engine produces stock more boost then the 02 Durramax. I'm sure we can move this post over to the 6.4L forum and get some better answers.

Do you know where the sensors are placed on each truck with respect to the turbo?

I think its just a Powerstroke thing, they seem to run hotter. My old cummins in general had much lower EGT's.

Your fine, 900 degrees is not hot at all if your reading Fahrenheit , i would be concerned if your higher than 1200 to 1250 degrees for any sustained amount of time. I have ran my truck at temps around 1320 degrees for over twenty minutes sustained on a hard 19 mile 8% grade pulling about 22,000 lbs, i wouldn't recommend that to anyone new to these diesel engines because anything above 1250 degrees other things must be monitored as well such as actual oil temps and coolant temps , I'm just using it as proof the engines can Handel the heat.
