H&S Performance Mini Maxx Programmer


I have read ZZ Diesel's disclaimer: 

The H&S Performance Mini Maxx is our most popular tuner. One part number fits the following vehicles:

  • Dodge Ram Cummins Diesel 6.7 2007-2012
  • Ford SuperDuty Powerstroke Diesel 6.4 / 6.7 2008-2015
  • Chevy / GMC Duramax Diesel LMM / LML 2007-2014

Fuel Mileage Gains
Depending on how restricted your catalytic converter and diesel particulate filter are; fuel mileage can vary. We typically see trucks that are equipped with a DPF getting 13-14mpg or less. With the Mini Maxx, total mileage is approx 18-19mpg or better. Larger tires and driving habits can effect these numbers.

Power Levels

Powerstroke 6.4 - 80,160, 250hp

Powerstroke 6.7 - 50,100,150hp

Duramax LMM - 60,120,175hp

Duramax LML - 50,100,150hp

Cummins - 60,120,175hp
