Eco Boost Owners - Anyone using a Tow Tune?
Anyone using a tow tune from a company like 5-Star? If so, does it make a difference? Are you using 87 or 91 octane?

I wonder how the new low-friction rear ends are doing in these powerhouses? The EB exceeds the HP/torque of the early 2 valve V-10's, and often F-250 towing capacity as well. But the old V-10's were ahead of a fuel-thirsty 10.5 inch Sterling gearset used in most 350's and even some 450's, I believe.
What is under the F-150 with 11k plus tow capacity? I thought they were just a 9.5 inch (EDIT: 9.75 inch) rear axle or thereabouts. Some new metallurgy at work here?
