Default Duramilage???

I just bought a 2016 duramax. I am pretty disappointed with the mileage I am getting. I bought this truck and wanted to leave it stock unlike my other duramax. I have been seeing the duramilage and like what it claims to do. Wondering if anyone has experience with it or knows of a better one that won't be traceable in the computer.

What are you doing with the truck? DD'ing it, towing or working it?

Depending on emissions laws in your state I would suggest Deleting the DPF and getting a nice EFI live tune. Should liven the truck up and gain you some mileage at the same time.

Thanks but not looking to void warranty. Looking for a untraceable tuner to increase fuel mileage. More power would be a plus but not necessary.

Pretty sure the TCM stores torque inputs. And whatever tune you run in the ECM, untraceable or not, will show up if your dealer really looks into it.

Nothing is "untraceable".

Gm has many ways to find out if any calibration is put into the system and or modifications with sensors. They have expected values stores in there calibrations so it will limp or flag a code of somethings off

^^^ This.

If you don't want to void the warranty, then don't mess with it and enjoy your crappy fuel economy.

Wouldn't do it. Buddy of mine tried one in his new 15. Caused a ton of issues, cost him a trip to the dealer on his dime, and took 4 months to get a refund on the device. The customer service is absolutely horrible. He had to make legal action threats just to get a response.
And I've always been told they improve over time? My 2011 lml is averaging 14-16 mixed and 18-22 highway depending on if it's in regen.

Do u have a way to monitor soot mass in the dpf? If so when it hits 40 to 45 grams. Go for a drive on Highway and let it burn off. More plugged the dpf more fuel it takes for it to get the can nice and toasty
