21 3.5L XLT 4x4 CC 5.5box 3.55 with Max Tow, leveled on 295/60-20's Nitto RG with 1" rear block.
I filled up my rear tires to 48psi and fronts to 38psi (E load)
I used a 22ft Speed loader trailer (2700lbs) towing a lifted 1st gen Tundra 4x4 roughly 500 miles.
The F150 towed it easily with a ton of power to spare and I could set the cruise going 70-75mph it never dropped below 7th gear going up hills, truck said I averaged 12.8mpg which i find hard to believe. It even settled into 10th gear on the flats in tow/haul. It was across Illinois & Iowa so only small hills. Very stable and felt like a 3/4 ton.

I got 16mpg towing this so 13 seems feasible.

When I towed my 9k lb camper with a 2019 5.0l I got 8mpg.
I’m curious to see what I get with my EB

3.5 ecoboost towing a 5500 lb travel trailer. I am getting about 9.5 mpg on average. I have seen 7 mpg and 11 mpg depending on if i drive aggressive or not.

Nice sharp white 300z TT. What year? What stage?
1991 TT 5Spd.

I don't know what "stage" things are since there's no hard and fast rules.

But basically everything but internals are upgraded. Made about 400whp years ago on a dyno. It's been sitting in my Dad's barn for a while. I bought my own house, finally, and it's gonna get a full resto-mod.

I would bet you get extremely similar results at the same speed. Eco or Boost. One at a time. But the EB will pull it better. Ride that wave of torque.

I had a 91TT 5Spd in Aztec Red; modded to stage 3+ and dyno'd at 395rhp back in the day.
Had to sell it since a new baby was on the way so priorities changed.
