Towing setting?

[fordmanmark1]

I have H&S XRT pro with some hot tunes loaded in it. Im running the mild tune now, what would be the best tune setting to run while pulling my 5th wheel next weekend? This will be the first time towing since the tunes have ben installed.

I got the XRT as well. I think if you go with the HD300 to stick with No Power (50HP) or Mild when towing. And do not use the Tow/Haul mode as it was not designed for the power increase. Also keep an eye on your EOT/ECT temps.

I will be towing a 5'er here in a few months in the hot Texas heat so I have been searching for the same info as well.

Check out hsperformance.com and go to the 6.4 forum threads. This same info is over there. Hope this helps.

I think it has to do more with the additional HP than with the shift schedule. I have heard guys use the tow/haul when going downhill to use it for braking but they turn it off once they reach a level plane.

But it doesnt hurt to use S1L when towing.

I have tried all the shift schedules but s2h and after dragging my 25ft gn around loaded and empty, on the flat and the hills, I went back to s2m. The early lockup in 4th was a pain in town and 5th tc lock in s2l was too low in the power band for my liking with the trailer. I still use tow/haul in the hills and especially downhill with a load so I'm not on the binders all the time. Seems to work great for me.
