High Exhaust Temp When Towing:Help

I have found that I have to really watch my exhaust temps when towing, particularly when going up hill. I have found that it can run at 1100deg and might spike to +1200deg if my RPM's go down.

I am running aftermarket exhaust, the previous owner put some sort of chip on it(can't tell what kind it is), and an AFE insert & DIY. I am towing about 7000-8000 lbs.

Any suggestions to cool better or help with this issue?

2001 PD Excursion:
Tow goodies
Some go fast parts
Big TV to keep the kids quiet
Upgraded stereo to keep the driver happy

It tows my race car like its not even there

When I pull the chip off, do I need to take anything into concideration? I did not install it, so any suggestions? I can see it on the board, but not sure how it went on or comes off. Do I need to open the box? I can see the chip on the board through the side.

It appears to have some towing mapping as it works with the torque converter when I am going down hill.

probably just the chip you got.. might want to get a custom one.

What RPM's are you towing at... you gotta keep it well above 2000 or it will get hot..

2001 - 14" OUO 525 - 38x15.5x20 Toyo & 20x12 Weld Cheyenne's. Hybrids, 38R, BTS, Spearco, Terminators..

From what I've read on here you can tow at 1200* all day long. Its when you go past that you need to worry.

The truck can run all day long at 1250 as well, but sustained over that should be kept to under 2-3 min. EGT's are controlled by good air flow and even better tunning. Since you have the airflow, you need better tuning. I tow a 10K TT all over the place and with DP's 60 tow I have never, never had to back off the go pedal due to high EGT's.

Just keep in mind if your tunes are lowered, you will have less power. I use my 70 tune all the time but have to keep an eye on the pyro. if I put it in my 50 tune I dont have to watch it but my truck feels so much more slugish. I pull a 12k 5er and usually start out a trip with 120 gal of fuel onboard

Just a basic 01 F350 CCLB SRW -Good from a far but far from good
