RE: Heavy Haul - Fuel Economy and Engine Life
you want it to last longer? --- drop the torque to just about 1790 ft-lbs, set the power to 605HP, and re-gear it taller (maybe 4.63's or 4.88's thereabouts) so that it can stay in the 1600 - 1900 rpm ranges all the time. Maybe also put a 500 series VGT on it to go with that for better heat xfer out of the engine too.

(18-speed w/24.5's)...

HP does not wear out the isx... torque does, and that 2050 torque in that X15 is all below 1300rpm where it tortures it.
