Tuning on a 2017 duramax

Ive looked everywhere, and mabye the numbers/parts just are not in yet, but has anyone tuned a 2017 yet? If so, what numbers did you see, and what kind of MPG did you get. If there is already a thread on this, a link would be great.

Thanks, I dont know much about this, but I wouldnt think the tunes would be as beneficial in the L5P as they were in my 2007 Classic because the L5P has more power to begin with. Would you think thats a fair assessment? As it stands the L5P has just a little less power than my 2007 C (tune, exhaust, cold air intake, down pipe). My main concern is gas mileage.

As part of the 2017 upgrades i think the injection got upgraded?
If thats the case for me on my tuned 15, that was my personal limiting factor as the truck would run out of fuel on aggressive tunes.
After driving my 17 for a bit, i think traction will be a problem when it get tuned....hehe

Haven't seen anything yet either, not even held held tuners. But I haven't paid much attention to that

definitely curious when tuning will be available. not really looking for HP gains, but have noticed a few things can be dialed in. if they can make the injection fueling noise quiet at all times and tune out the odd knock when you let off the throttle.

I have a bit of a hard time understanding giving up your factory warranty on new unproven motor and misc systems on it or is it just wanting it out weighs the cost, now I am not criticizing those who want to so don't freak out, I am trying to learn if there is a loophole so I can do things to my 15 ?
