best tuner for the LMM

I would go to youtube and search Dmax and exhaust maybe add a few brand names in there. So you can hear the exhaust and pick one you like. PPE is the best tuner, but if you want to make your own or get custom tunes EFI is the top of the line. EFI, PPE and Quadzilla all can disable the dpf not sure about any others.
