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

My 6.0 only has the 4 spd trans, but I've found it will hold speed better at 68-70, than in the low 60s. It seems those few extra rpms bump it up where it is not as likely to downshift on those little rises.
Also if the terrain is kinda rolling and it is downshifting, I drop it to 3rd gear and it spins about 3000rpm, and does well. Actually I don't notice a difference in MPGs towing in 3rd vs 4th, it sucks it all down either way :)
I had this happen with our last motorhome. If I drove 62 or 63 mph it would shift on any little rise in the road. If I drove 65 / 66 mph it would shift a lot less. I have tried that with this truck but it doesn’t seem to make a difference.
