I do not have an LML, mine is the LBZ. I do have Cory's tunes on my truck. The only things I had to delete was the EGR valve and the intake heater. I had an Edge Juice on my truck before and when I switched to EFI Live my fuel mileage went up 3 mpg both hwy and city.
You can get emissions intact tuning for the LML, but I don't think Cory offers it. I believe Idaho Rob and Duramax Tuner both do. When you delete your truck you have to buy everything separate, but some of the vendors may build a package for you. I recommend either PPEI or Alligator Performance. They are both very helpful and knowledgeable.
