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

Just a quick update with m my 2012 with the 5 star tune. I have gone from a fuel mileage average last year of 5.3. So far on this trip I have averaged 6.2. This is with a generator running for 3 hours one day, off the next but going through the mountains. This brings up another plus……no longer am I down to 40mph going up a grade WV and VA. I64 East. Yes I slow down but the slowest I was at was 50mph. So far I’m loving it and it’s everything I’ve expected it to be.
