I came close to ordering a new 2011, but when I read 2012 will be 750+ foot pounds of torque, with a new 8 speed, my good running 2005 will stay with me for another year plus, with that added power there will I am betting pee fluid included like GM and FMC' and that is fine, it should let Cummins cut back a little on EGR, and that will help with the turbo sooting.
