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
I saw a Charger that got a tuner on it (Diablosport Predator) before its first oil change.
The car is still running, 15 years and almost 400,000 miles later. The engine and transmission are internally untouched. I recall it turned 200,000 miles at over 100MPH and 300,000 miles enroute to a HPDE.
