Towing power

[Frankf250]

Hi all,
I have had my 07 6.0 for about 5 months and it's my first diesel. My bro had a 04 and he got a 2011. Anyway my question is he never had problems towing and I seem to not be able to do more than 55 up any kind of hill. He could do 80 up the same hill with a close size trailer. It's a 30' 5th wheel. Just under 10k. I had it at Ford and they looked over everything and said all test were past. Truck only has 30k an I got it with 26k. Anyone had any experience with this? Thanks for your help.

Is yours tuned? What mods do you have if any? I have never used mine to tow with stock tuning, I use a tow tune. It only adds a little bit of power though. Seems to me like your truck should do better than that. I can tow 15k of hay anywhere and at any reasonable speed, faster than 55 for sure.

I haven't done anything to the truck yet.. Other than stereo, light bar, wheels, power running boards, so no engine work yet. I want a sct but trying to save a little $ maybe that's all it needs to help out a little. And monitoring system of course

Edge Insight to see what kinda shape your coolers are in first, then tune.

also pull your IAT2 sensor out (located in the intake by the fuel filter) and make sure it is not covered in caked on soot.

Some other things unmentioned that affect towing performance are the possibility of different differential gearing in the rearend between the trucks, a lift kit on either truck, 4x4 option on either truck (added weight), CC vs SC vs Reg cab, long bed vs short bed, and manual vs automatic transmission.

Something isn't right if it is struggling that much to pull less than 10k. I've road in numerous 6.0's that was bone stock and pulled alot heavier than that with no issue.... And could definitely get above 55mph! You could also pull the EBP (exhaust back pressure) sensor and make sure its not covered in soot and the tube isn't clogged. This controls boost and could affect mileage also.

I just had about 17k behind my truck and did 65 with no problem on my tow tune.

Thanks guys I'll be checking those things out. How about checking the EGR?

I bought the new gasket kit from ford ($7) so I think I'll pull that and clean it too. What's the best way to clean it? Also does anyone else run Diesel Kleen in their fuel? I just started so hope it keeps the injectors clean
