I bit the bullet and finally plugged my old InTune from my GTO into the Sierra yesterday. Played with a few settings, but mainly just straight canned Diablo tune and Firm shift trans tune.
Truck didn't explode. GM didn't call me through the Onstar to tell me I angered the warranty gods. It was a good day.

Pretty much. Its just a gussied up base truck without having to go on up to SLE trim. Like the Silverado CST. Plus G80.
I wondered tbat myself but meh.
Joke is on everyone else though, this truck has the driver's assist handle.
2015 Sierra Elevation Edition - 5.3/3.42/4x4
And it's already reminding me how much of a PITA it is keeping a black vehicle clean.
Only bad thing is not E85. Hopefully I can fix that.
