I forgot to mention the first thing I did was add the GM performance exhaust which isn’t much of a performance upgrade, but does greatly improve the sound without pissing off your neighbors.
Another thing worth mentioning is as far as I can tell the OEM GM LGX (V6) Cold Air Intake is as yet unsupported for 2018. For 2016-2017 the intake comes with a code that gets you a free dealership provided tune that goes with the intake. I suspect they haven’t developed the tune parameters for 2018, which is why this year isn’t supported. There’s several aftermarket CAIs which will work, but they do not come with a tune.
