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

Tuners won't do anything for engine output on a normally aspirated gas engine. That's already been maximized by the manufacturer.
All tuners do is give your subconscious a lead foot so you stomp on the pedal harder, say, "YEAH! I HAAAAAAVE THE POWERRRRRR!" to yourself, then find out three days later that nothing really changed and there's a hole in your wallet where several hundred dollars used to be.
Not true for regular vehicles.
Performance can be measured and the tunes increase HP and torque.
You get marginal increases at WIDE OPEN THROTTLE.
How often do you drive at WOT? Unless you're drag racing, almost never.
