Buy the "Range Technology" device if that is all the person is after. You'll waste so much money using HP Tuners for only that.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
Yes, super easy to disable. You can also disable the auto start/stop.

THANKS

Cheaper to buy a plug in device if all you want is the AFM off.
