2008 2500HD Duramax Diesel LMM
model # 7176
software revision on the Predator or Trinity N/A
specific information relating to any issue or question you may have

I was wondering what the best setting to choose
was for MPG. I pull a horse trailer about once a month. My truck is a daily driver. I saw in other post people use the 100HP TUNE. Does this cause more wear and tear on the truck/motor? What would you recommend using? I am seeking the best MPG HP/TRQ is not an issue. I have only an K&N Air Intake as the only mod.

I forgot to ask, what is the tow tune exactly? Is it a HP/Torque increase and better mPG? Regarding the MPG everyday driving would I use the 60 or 80 for best MPG? I am looking for mpg over power.

I have a K&N intake, I was wondering if it would be possible someone could make an updated tune for it as well? or Can I just run one of the stock settings?

tow is 40 hp/100 ft/lbs.

without towing, the higher power tunes will yield best mileage.

Thanks Mike. What do you recommend for daily driving for the best mpg? I am not to worried about the HP just the MPG.

Also do you offer a tune with a K&N intake ? only mod I have? will my truck run with the stock tune with the K&N?

many users get their best mileage running the 120 tune with a light foot

I can get 23-24 MPG from our 06 LLY on the highway at 75 mph like that
