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?

Even during a cleaning cycle around 1100-1200 is the norm for me.
Running WOT with GCVWR of 23K going up long grades I only net around 1350 EGT's.
