So I just bought my first diesel, 2020 ram 2500 6.7 Cummins. 5in lift with 37s, with no load I’m averaging 15 mpg but with but with pulling my trailer or boat I’m gettin around 7.
I’ve been looking around for a tuner to help improve my mpg with and without a trailer but can’t find any that are compatible with the 2020 yet.
Do y’all have know of any tuners that are compatible that can help me out?
