Tow/Haul when starting

From the tech folder I saw an article about setting up my truck to automatically turn on tow haul mode. I did some searching around on the forums for more info on this and didn't find a whole lot. I found 1 thread where a person reported improved fuel economy when running with it on in town and of course some other benefits. My question on this is how to use this. Start the truck out from stop in tow haul mode but then what? Turn it off at 55 or just leave it it that mode all the time or keep it at 2000 rpm? So at any rate I would appreciate some feedback here. I sure to like tow haul especially when slowing down. Love that the truck gears down feels like I'm back in my old standard 7.3 from the bygone years.

Once you're above 55 MPH it doesn't matter if you are in tow/haul or not. Either way it's going to be in overdrive.

Interesting. Would leaving it in tow/haul in the city improve fuel mileage?

I don't know the answer to that. I wouldn't expect it to, because it shifts at higher RPM. Higher RPM shifts tend to lower fuel economy.

Subscribing. I, too, would be interested in this. I tow nearly every day and often forget to put it into tow mode.

Just as an aside this is the thread I mentioned in my original post. Also I should clarify the tech folder doesn't say everyone should do this for any particular benefit just how to for those who need or want to. I've heard over the years from folks who say you should to benefit the transmission and truck but was never sure why. In searching I found the post below which prompted me to ask directly about it.

It would seem that some of the tunes that change shift points would have the same affect. I run and Innovative Xtreme X that shifts at a higher RPM and seem to get the best mileage with that tune.

Well now that I know it’s not gonna do any damage to drive in tow mode full time, I just need to train my brain to flip the switch just like I buckle my seatbelt. If I can’t train myself then I’ll invest in the mod.

Those who know me here, know I'm not normal... after driving with tow/haul engaged in town, I still push the button and did step up to the stage 2 turbo. I'm a solid 15+ mpg in town and easily hit 20+ on the highway. Just this last weekend averaged 19.7mpg with a 6k trailer behind me.... but I have considerable mods to the truck and foot pressure dictates mileage. Light foot will get me better mileage or worse when heavy footed.

when not pushed to tow/haul I'm in the 14-15 mpg range all day long in town and the truck is quieter.

straight pipe and turbo whistle are very prominent in tow/haul!

I will warn you, your stuff better be straight. It will point out weak injectors and so forth as higher RPM tends to amplify everything.
