How'd my rig do...
First run as a hotshot. Ran about 15k behind her from denver to flagstaff. I took i-70 through Utah and 191 down. It was pretty hilly/mountainous.
I personally think she did well, but I'm new to the 6.0 world so I'd like some feedback.
Most of the day was 97 degrees + she ran a 15 delta or less when on the flats but when it came to climbing a decent hill she hit a 23 degree spread between coolant and oil Temps. At one point I saw 223 ECT and 243 EOT. Tranny ran well til the 6-7% grades then she saw a high of 190 degrees.
I tried keeping my egt below 1200 but I caught myself a couple times at 1300ish and quickly let off the throttle.
Other than hills, she did better than I thought. This is the heaviest load I'll pull. Any cause for concerns here?

If I'm empty, it never goes over a 10 spread

That's great to hear. I shouldn't be worried about such a big spread? I thought if it was over 15 degrees it was cause for concern, but I don't know if that was under severe conditions.

And run it in tow-haul on hills or pull it down a gear to get the RPM up. Makes the fan come on strong, let's the gears do the work and keeps EGTs down and should keep the temps down as well.
Did good.
The 15 spread is flat ground, no load or towing, at 2000RPM for 15 minutes.

The official test is done with an ECT of no less than 190 degrees. If you have 189 or less ECT any testing is invalid.
As for "official" tests It was originally 25 degrees difference normal driving, then 15 degrees WOT to 49 mph then to now it is 10 degrees @ 1800 rpm driving 15 minutes.
Service Manual Procedure:
NOTE: Verify that no accessories are in use (engine block or oil heaters).
Clear all the DTCs.
Cold soak the vehicle at ambient temperature for a minimum of 10 hours.
Ignition ON, engine OFF.
Access the PCM and monitor the ECT (TEMP) PID.
Access the PCM and monitor the EOT (TEMP) PID.
Access the PCM and monitor the RPM (RPM) PID.
Access the PCM and monitor the MFDES (MASS) PID.
Record the ECT and EOT sensor temperature values.
Drive the vehicle at an engine speed greater than 1,800 RPM and 15 mg/stroke MFDES for at least 15 minutes. Select the appropriate gear to achieve the operating conditions.
Does the ECT PID and EOT PID temperature values change by a minimum of 6ºC (10ºF) from when the ignition ON, engine OFF valves were recorded?
IF Yes
INSTALL a new oil cooler kit.
IF NO
INSTALL a new ECT sensor or EOT sensor in question.
CLEAR the DTCs. REPEAT the self-test.
In a nutshell 1800 rpm is basically 65 mph for most trucks.

15 minutes??
Your oil cooler could take longer to climb out of 15* spec but if it cant cool its toast IMO
his sounds good
I think the Fan step is set to close to defuel point its programing problem later strategy seams to kick fan in earlier
guessing 03-04 truck

05 it did well climing out. I mean once I hit flats or smaller hills she cooled within 10 minutes would be my guess
