Anyone towed with Ecoboost?

Has anyone upgraded from the 3V 5.4 to Ecoboot and towed the same load, say 5 to 6K pounds? Really curious and considering the ecoboost. Especially if performance is better at altitude. (did a little searching but saw no comparison, maybe too early)

Lots more power with a far better torque curve, better transmission, and forced induction....ecoboost will destroy the 5.4L towing 6k pounds at elevation (no power loss for forced induction engines at elevation while N/A engines loss 3% power per 1000ft). Some people got to compare then head to head in the towing demos they did a while back, search the 09-11 section.

EB has only been for sale for about a month, so even the first owners don't have much time/miles/experience with them, like even filling the tank more than once. And it's winter in most of the country, not generally towing season yet.

Theoretically, the EB should have plenty of an advantage over the 5.4L. More torque at 1700rpm-5000rpm than the 5.4L has at its peak, let alone across the usable range. plus the lower power loss (not nothing, but smaller than naturally aspirated) at higher altitudes.
