Whats the best tuner for a LMM Duramax. I know ppe is a good one but what about EFI Live, isnt that kinda like a sct x3 because you can put custom tunes on it. I have a friend that is wanting to ditch the dpf and he asked me but i realy dont have a clue. What about a dodge. My dad has a 08 6.7 and there isnt a week that goes by that it doesnt have a clogged dpf. I know H&S has stuff out for them but what about the edge racing evolution or cts or whatever it is. Any help or comments is appreciated. Thanks!
