Anyone else: Tune transformed the car, but what should I log?

Running a conservative tune and the car feels great. I don't want to judge reliability by seat-of-the-pants though. Which parameters would you log periodically—fuel trims, knock, boost target, temperatures, something else? If I fix it I'll come back and update the thread.

Write down what you already tried. A second data point from another 2025 Porsche Macan owner helps more than a generic diagnosis. I'd do that before spending real money. This is from a 2025 Porsche Macan in Michigan. Time, temperature, and whether it's in gear are the notes that actually help a shop. Not trying to scare you — just skip the expensive first guess. Might be overthinking it, but I'd rather overthink than overspend.

I parked the 2025 Porsche Macan and wrote down what I already tested so I'm not repeating myself. I'm in no rush to be a hero on it.

Owner notes beat generic advice here. On the 2025 Porsche Macan in Michigan, I'd fix the thing you'll notice every day before chasing spec-sheet extras. I'd do that before spending real money. On “tune transformed the car, but what should,” that was the fork that mattered for me. When does it actually happen? That's my plan before I call anyone.

I'd keep this practical. Verify the cheap/easy branch on the 2025 Porsche Macan before a big repair or a big spend. I'd do that before spending real money. This is from a 2025 Porsche Macan in Michigan. Run the total, not the monthly, before you commit. This is me being the wet blanket on purpose.
