EFI Live (LMM)

Make your Duramax LMM come alive with our custom EFI Live tuning.  From mild tunes to wild 200 HP plus tunes, there is something to fit your needs.  We offer other tuning variations: rumble at idle like the LB7 trucks, super hiss tunes and turbo brake tuning comes standard on all of our tow tunes.  Want a high idle on demand?  We can do that too.  Be the envy of all your friends this weekend when you roll up in a custom EFI Live tuned Duramax LMM!
