Truck weighs about 10200 loaded for long trips; trailer about 17400 = 27600gross.
Using an H&S MiniMaxx tuner, DPF/DOC deleted, EGR deactivated, 4" exhaust w/muffler. Temps are only a problem if I try to beat everyone to the top of the pass...the real benefit of the tuner is no more regens at the worst possible time, there is no "2-5 mpg" improvement in mileage that I can see.
These tuners WILL destroy an engine if run at highest level under load.
If I could afford a new truck, would not consider using one as all the new ones have plenty of power as built--trying to improve on them is mostly pointless, and the delete tuners are now a black-market item due to pressure by EPA.
Prepping for repeat of 2012 AK trip this June.
