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've had various tuners in the past and to really feel anything you had to run the high octane tune....due to timing advance. All other options like tow and economy only changed shift points.
If you choose to tow with the performance tune " I did ", keep an eye on temps.
On the Ford site, many members speak highly of 4-star.
My 2021 7.3 does an admirable job towing and is under warranty so leaving it stock.
