(2013/2014 is a slpit year in ECM models, easiest way to determine if you need the 2008-2013.5 unit is to look at your diagnostic connector under your dash. If it is round then you need the 2008-2013.5 HDT-MackMP7/8 unit, if it is rectangular you will need the HDT-MackPM-14+ unit)

This unit plugs into the engine computer and controls injector timing and injected quantities helping the engine with throttle response and lowering the torque curve by spooling the turbocharger faster. This unit also will allow for all the original emissions controls to function as stock and properly.  One key benefit to this style system is when the truck goes in for service any dealer in the country can repair / update controllers WITHOUT risk of over writing a "tuned" controller. Also you can revert the truck back to completely stock in a matter of minutes by using our Bypass / Wash connector which allows the harness to remain plugged in but simply removes the power box for a hassle free task!
