I can't say enough good things about Kennedy Diesel and their custom tunes. I have had many tuners/programmers in the past (most of the major name brands), and nothing to date compairs to Kennedy. My EGT's are lower, my tranny temps are lower, better fuel economy (around 19.5 mpg on the highway cruising at 75), and the truck pulls better than it ever has in the past. Thanks John!

What were you seeing for mpg prior to Kennedy, both stock and other tuners? I must be the only one who gets lower mpg without my DPF :o:

do u know if they make a module for the lmm?

Kennedy tunes your ECM or you purchase a second ECM (which I suggest).

I agree completely with 08Duramax, this is the best tune I have had in my 4 Duramax's I have owned. There is another thread in this section that talks more about Kennedy's tune for the LMM
