2021 Chevrolet Silverado 1500 — conservative tune feels great — what should I log?

2021 Chevrolet Silverado 1500 LTZ 6.2, about 54,500 miles. I do not want to judge a tune only by how fast the car feels. Which parameters are worth logging periodically if the goal is catching fuel, knock, boost or temperature problems early?

Owner notes beat generic advice here. On the 2021 Chevrolet Silverado 1500 in Austin, I'd fix the thing you'll notice every day before chasing spec-sheet extras. Then you'll know the next fork. On “conservative tune feels great — what should,” that was the fork that mattered for me. I'd want that in writing, not as a promise. Wrote this up on my lunch break.

Write down what you already tried. A second data point from another 2021 Chevrolet Silverado 1500 owner helps more than a generic diagnosis. I'd do that before spending real money. Had a similar mess a couple years ago and that's what finally sorted it. If this is nothing, great. I want that in data.

Don't overfit one forum story to your car. If it still isn't clear on the 2021 Chevrolet Silverado 1500, a specialist hour can be cheaper than another round of parts. Then you'll know the next fork. Had a similar mess a couple years ago and that's what finally sorted it. I'm keeping receipts and dates in one folder.
