Heavy Towing with DP Tuner and 6 Speed

So i just bought an 01 F350 a few weeks back and Im getting ready to go on a long road trip pulling around 15k lbs. The truck is pretty well setup with fuel lab RR fuel system by Irate Diesel, Full force 160cc single shot injectors, 4" Ported Big Bad Wolf turbo from Sinister diesel, afe intake, 4" exhaust and custom tuning from DP tuner. O ya and it has a 6 speed with a newer clutch!!

My DP tuner has a 20HP tow, 60HP daily and 120HP setting. My question is, I have pulled the trailer empty with the 60hp setting and it pulled great and never got hot at all on the egt's. What is the limit for towing heavy on tunes?

15 F350 CCLB 6.7 Many mods to come.....

The heavier the trailer the lower you want too go with the tow setting, I would use the 20hp tow for that heavy of a trailer.

the 20hp tow felt pretty gutless, what am I going to hurt by running a higher tune?

You run the chance of unsafe EGTs damaging pistons and the turbo, mostly. If the EGTs are constantly hot, it's possible to overheat it, too.

Personally, I'd try it and keep a very close eye on the pyrometer, if it's getting too hot (over 1200 constantly), bump it down to the 20 horse setting.

You might also consider eventually having the chip reburned with a 40 horse tow tune.

last time i towed the trailer empty (11,750lbs) on the 60hp i dont think it ever even got to 1200 and that was pulling some pretty big grades too

The tow tunes are created with the weight limit in mind for safety. If you decide to run a higher HP tune, you run the risk of higher EGT's as the weight increases.

You may want to try towing with our 40HP Tow. It seems like it would be the correct match for your situation.

well i just got back from a 1600+ mile road trip pulling my 40ft toy hauler and the trailer was about 15,500 lbs fully loaded. I went from northern Ca up to idaho so I pulled some pretty steep grades and i pretty much towed off my pyro the entire time. I started out in the 20HP tow tune and it was pretty gutless so I switched to the 60HP tune and I was able to pull most of the time on that setting. I never let the pyro gauge get past 1200 but it would get hot fast once the motor would start to lug and I would have to downshift. Also it was very hot out like close to 100 degrees outside

So Im thinking i want to upgrade the cooling and either get a bigger intercooler or possibly water meth or even both.What do you all think?

If you went 4th of July I bet it was packed. Any accidents that you saw? Occasionally when it's busy there can be a few reckless people. Glad you liked it.
