Default 2012, Supercrew, Platinum, eco boost, fuel economy

Not much to tell other than still evaluating the power train. ...
Will it pull YES....!
Does it deliver what I anticipated fuel economy NO!
At 19,458 miles this rig has been recalibrated three times and suffers from cold start strategy that really compromises overall fuel economy. Don't ever let it idle, you can kiss your fuel economy Goodbye!
My rig is a maximum trailer tow 373 4x4 Super Crew with a Leer cap.
Does the maximum trailer tow impact the overall mpg, you betcha! This, however, does not justify 13.5/13.8cty - 16.5/16.9 hwy under 70 mph since
new. The same rig with a reduced a ratio may deliver up to 22.0mpg above 70mph
STATS: Towing? 8000# 7.8-8.8 at 68mph. From 14,000 /19,700 with summer fuel and warmer temps (55/85 degrees ambient), I have seen up to 20.1 mpg but this is rare.
Real world is 14.8 cty/18.9 hwy summer, 13.5/14.5cty-16.5/18.0hwy winter:
Recognize the 2012 has an electric vacuum pump subject to condensation which in cold weather can freeze leaving you with not only poor performance but a fading brake pedal. Only option, replace the pump. Some have reported slugging when the turbos loading with water as well but I must confess I never experienced any transmission nor calibration issues short of POOR fuel economy.
