Tuner like “5 Star Tune “
I have a 2019 3500 Silverado 6.0 gas. Has anyone used a tuner like a “5 star tune “ ? I was wondering if or how they work before I purchase one and which brand I should buy? Thanks

Maybe you could manually downshift and just run one gear lower all the time to avoid downshifting? Sometimes running at a slightly higher or lower speed may help as well.
