MM3 Touch Display and MM3 Controller FLEET (2011-2019 Powerstroke 6.7L)This package is meant for Fleet companies with multiple vehicles that they plan on tuning with one unit. These are guys that dont want the MM3 device in each vehicle, so they prefer a more affordable option to get their vehicles running at their best, then back out on the job. These units come registered with a greater number of vin licenses compared to the standard MM3 units. A new support pack purchase is still required with each truck needing tuned.
