I have a 2008 2500HD mostly stock that I am using to tow our 2011 24ft Fox Mountain 5r. I haven't towed it farther than about 100 miles from home on mostly flat highway but that will change next month when we go to Prescott, AZ for 4th of July. I spend some time on the Diesel truck forums often and what I have read about EGT's concerns me? People with stock exhaust (With the DPF) discuss having trouble keeping EGT's below 1300? So their solution is to straight pipe the exhaust and get a programmer to delete the DPF... I would like to do this just don't want to spend the $1500 bucks it would cost to do it right now. So I'm wondering if anyone here is having this problem? And if so what have you done?
I know they think those temps are high and they really are for an older engine.
Because of the retarded timing and build materials, those engines can easily take any EGT stock tuning results in - it isn't "too hot".
They're built pretty much idiot proof so that they can be run full throttle at max load almost indefinitely. IMHO, you don't "need" to be concerned about a healthy stock engine having excessive EGT's.

Have an 07 2500hd Srw dmax, stock, been pullin my 38.5' 10600 lb(dry) 5r around with NO PROBLEMS. And Ohio or NJ are the nearest flat roads! Lol
Hit the cat scales, if you're under your gcwr and axle weights there is little to worry about.
Some folks can't leave well enough alone, excluding the new scorpion ford powerstoke no stock diesel pu combo can touch the stock LMM.
Make sure you do the tranny service, mines recd at 50k miles.
Other than that, just drive, mine loves to work it seems...

You are better off leaving well enough alone. Use the money for traveling. Let the computer do it's job and don't worry about the egt's because the computer isn't going to let them get excessive or too high.

If you do anything at all (neither is needed) have an EGT gauge installed pre-turbo. When you see temp passing 1250 while climbing a long grade - just get out of the accelerator a little and they will instantly drop.
My advice: stay away from a chip/tuner.

I've owned a stock '05 Duramax since new. The drivetrain is bone stock. I regularly gross 18,000 to 24,000. The truck has been perfect. I don't have a EGT guage.
I did own a stock '07.5 Duramx. It was bone stock. I grossed the same weight. It was also perfect and had no EGT gauge.
I don't see the need to add things to these trucks/engines. They are darn near perfect from the factory. The last time my transmission man service the '05 Allison with 140,000 miles he said it was so clean he couldn't believe I had so many miles on it.

Yup, or drop the tranny down a gear and get improved temps.
My 2001 Chevy DuraMax has 217,000 mi. and is stock. Toy Hauler probably a little over 10,000 lbs loaded. Have pulled from east coast Maryland to Utah, Watkins Glen area Ny, Pa, and Misouri roughly 9,000 mi. total.
No problems here.
