Hey guys, just bought my first Duramax. 07 3500 LBZ all stock with 100,000 miles on it. I really just want a little better mpg and a bump in HP when towing my 5th wheel. I don't want to tear up the truck, its in great shape and I want to have it for a long time. I see so many options so I just wanted some opinions. Thanks

First off congrats!
That's easy to do, buy efi live from a trusted tuner/vendor. Upgrade the springs in your transmission to hold better. Lookup transgo Jr.
Removing all the emissions crap will net you the best increase. Unless you're in a strict emissions state.
If you want to run a slightly hotter tune while towing you MUST run a egt gauge at minimum.
If you have any questions just ask
