Depends on what you are going for. First and foremost the deletes need to be done, both EGR and DPF. then after that the MP-8 is nice for a little MPG boost, and the PMT is good for some extra power. With both of those you are going to need a FASS or Airdog to get all out of them. At that point you should be running right about 450 HP and getting 19 MPG avg.
