6.0 to the rescue!

So I got a phone call Friday night that my bro in law's Cummins has spit a torque converter on the drag strip at TS in Kentucky and he needs me to bring a trailer to get it. Bad thing is the transmission is a fully built ATS that is only 4 months old So I get hooked up to a 30ft gooseneck and head that way from Tuscaloosa, Al. early Saturday morning running stock tuning because I let my dad borrow my SCT for the trip. I was actually surprised how well it pulled on stock tuning. The trailer weighed 6700 according to a tag on it. I forgot to reset my trip meter but it burned a full tank of fuel going there. I was running 80mph the whole time but I still thought that's pretty awful fuel mileage. Anyhow got his truck loaded (6.7 megacab ~ 8400lbs) and got my programmer back off my dads truck and loaded the 50hp Tow Tune. I filled the truck back up and reset the trip meter this time. We got within a hour from home and i had a little over a quarter of a tank so we stopped and capped it off. I got to check my mileage this time and it was indeed awful = 9.2mpg! I know it was pulling a little over 15k lbs but why is it so low?? Is it because I was running 75mph the whole way back or because I really need a custom tow tune? I've been planning to get my FICM tuned to help me some and saving for a turbo. I really need to do something about the mileage towing. Also, twice when I stopped I saw a white cloud of smoke come out the exhaust and then go away. Truck never ran rough or nothing. Could that be the turbo going out? I know it's had a hard life of over spooling lol

I reset my speedometer when i put the 35s on with a Ford IDM at the dealer. (Got a friend that works there). Checked it with a GPS and it's dead on.

I get 5-9 pulling, I've been as low as 3, short trips are always better, on the longer open roads you got wind, hills that hurt your fuel. I would still get a custom tow tune, they are nice.

I'd say its a combo of your 35s and doing 80. There's a thread over on the nation that talks about how our trucks have double the drag at 70 than from 55. So 80 is worse yet. I'd bet if you slowed her down a ways your number would go up. JMO

Thanks for the replies guys. Yea I didn't try going slower than 75 because it seemed like if I ever let it fall around 70mph then it didn't have enough power and it would downshift and rpm's scream. If I kept it up around 2k rpm in overdrive it done a lot better. Just so happens that 2k is about 77mph because I'm stock gears and 35s. Do y'all run 55-60 and just let it stay out of overdrive and revved up?

Also, any thoughts on what the white cloud of smoke could of been? Turbo oil seal going out?

It's a 6.0, we all see white clouds from time to time.

Could be a turbo seal, or maybe you just want it to be a turbo seal so you can get a new turbo
