On the 6.7 ltrs the mp-8 or the epp is adjustable from 0% to 100%. No exact settings.Guys seem to be running the MP-8 and or Extreme Power Puck without issues. They are both pretty much the same thing. 3 power settings with a dash mounted knob. Stock, 50 hp, and 90/100 hp. You can leave it in stock for day to day driving and then turn it up for towing and or fun runs. I'm in the same boat, looking for something to run with the DPF. Most folks will just tell you to do the deletes though.
I am thinking the same thing as well.:thumbsup:I'm going to keep my truck stock until the warranty runs out, but I want to purchase a chip/programmer that will cover all my problems once I do the deletes. Which one works well with all the crap on, but will allow me to upgrade later? I don't want to buy another chip/programmer later!
