 Well it's now been 6 months with my new diesel and it's been great!  The only thing I took the truck in for was an update to flash the truck to 400 hp, 800 ft. lb of torque.  This new diesel has been a major success so far, don't believe some of the negative reviews as they are probably being submitted by competitors. Ford seems to really be on top of this diesel and wants feedback from its customers.
