Duramax LML Best Tune or no Tune?

[geeman]

1st LOVE the Diesel but just curious what you guys are doing to make her better.

I have been reading a lot lately about aftermarket Tunes and trying to figure out what is real world and what is just sales pitch.

Summer I pull a 8500# TT and winter a 2500# snowmobile trailer. I know several guys that have done a tune and picked up 2-6 MPG and that is what I am looking for. Pretty sure the EFI Live or Autocal is the way to go.

What do you think? What have you done? What real world results are you getting?

Did you do the deletes?

I know the older LBZ type trucks rocked with the tunes and wonder about the LML specifically.

Thanks!!
