I have a 2007 with a 6.7 engine. I am about to hit the 100,000 mile mark and would like to know what the members would recommend to boost performance and mileage. I tow 12,000 pounds with my truck and get 9.3 miles to the gallon on the average. any suggestions would be appreciated.

Thanks
John

I put a tuner on my truck and did a DPF delete and went from 17 to 22 mpg.
What tuner / tune and what settings? 17Mpg stock is pretty impressive. I get about 18-19 tuned in town.
