It was a great time as always thanks to our host. I was very impressed with the eco-boost as well. John and I had a lengthy discussion about the abilites. I drove it several miles as well up a long grade and it was able to hold the speed limit.
Some downshifting which you would expect but the transmission was well integrated and was seamless in delivering the power.
I too started in 4x4 for my run as I did not want to spin my tires. What I did not do was a boosted launch for my 6.4. So there was a brief delay while my turbo's spun up.
On a program note I came out for a four day weekend with my 5er. I crossed the scales in Hagerstown, MD at 23,050 for the trip. I seem to run hotter than some of the others but always have. I have 82K on the ODO and 2150 hrs (approx).
