towing 19,000lb with 120 tune

[roondog]

i towed my 9 horse horse trailer loaded down with all my show sutff and horses it ways around 19,000lb the tow setting was great. i would hit 1300F egt on every hill but other than that it was great. do you think the 120hp tune from the 1.22 revision will put my egts to high. please chime in if anyone has hauled anything this heavy on that tuune.

i would be afraid of an early turbo failure doing this.

Yeah if its hitting 1300F with the towing tune......and you better believe that the EGT's will be higher with the race tune

At 1300*F I would already be on the edge.
Like Clay said; I'd be worried about turbo seals.
Where are you reading your EGT's? Pre or Post Turbo?

Well as I understand it these trucks are built to run hot.....regen sees temps above 1250F for long periods of time.....hell Matt has hit 2050F with no problems...yet .........but still I wouldn't run the race tune, even when I tow, I bump it down to the 50HP tow tune on mine......I have no interest in racing or runnin 90+ when I'm haulin a load

I towed a travel trailer a little ways on the 120. Didn't like it too much. Turbo stayed spooled the whole time, switched to trailer mode and could pull easy at 70 in OD stayed right under 20lbs of boost on flat ground and only to about 32 psi over bridges with ease, never downshifting once. It wasn't 19000lbs, but worked a lot better on 8500. I didn't leave it on 120 long enough to check, but I would guess mileage would be quite a bit better on the trailer mode too.

i know mines not a 6.4, but I always tow with mine in the race settings with that much weight or more. it spools faster, and the egts seem to stay about the same. Of course, I've got the water inj. to help with that also. I'd say give it a shot, just watch it closely. You may just have to stop and change back to the tow tune if it gets out of hand

[roondog]

its pre turbo

In regards to the 1300* reading, I have an 08 F350 w/ the 6.4. I run a Spartan Phalanx tuner and have as one of my tunes the stock file w/ dpf delete. On this tune towing about 19K the EGT's will hit the high 1300's and occasionally will go over 1400* so I doubt your going to hurt the truck at all if you keep the EGT's in this range. I towed also with the 150 tune and if the EGT's get over 1400* the program will defuel the engine to keep the EGTs from getting too high. So even with the 150 tune they ran about like the stock EGT's.

I tow with the 250 tune all the time. I have a f550 and the combination of truck and trailer is 36,000 to 40,000 at times. I have seen egts at 1800 once for about 5 seconds. I watch the oil,coolant,and trany temps more than anything else. The biggest thing is to keep your foot out of it!!!!!!!
