Best Gas truck tuner

[jstone]

I have a 2015 6.0L Silverado. What would be a good tuner for it? Do you have one? If so what do you have and do you like it?

Thanks
Jeff

I really like the tunes they made for me.

Isnt one.  Tuned from factory at such a high level it is a waste of $ for 5hp.  Don't believe the hype, make em prove it, do research.  Unless serious mods are done and custom tunes it is waste of $ imop.,

Completely agree.
Unless you have a turbocharged or supercharged engine, don't bother.
All hype, unless you can change the tranny shift mapping.

I tuned my v10 for the trans mostly, but 5 star did wrench a surprising amount of power out of it too.

5 star is awesome, but I think there are better tuners for the Chevy out there. Black bear, and others, specialize in making the ls series powerhouses.

+1 on blackbear custom tunes

For a gm find someone that has HPtuners and knows how to use it. It can adjust shift points and pressures in the trans as well as most anything in the engine control module and is pc based. I had it done on my 08 5.3 after the engine rebuild and it was unbelievable the difference it made.
