2023 Mercedes-AMG C43 — conservative tune feels great — what should I log?

Log the conditions before you spend. A pressure test beats staring at a dry driveway if the 2023 Mercedes-AMG C43 is losing coolant with no puddle. That's the branch I'd chase this week. On “amg c43 — conservative tune feels great,” that was the fork that mattered for me. Write the result down so the next test isn't a repeat of the last one. If that fails I'll eat the diagnostic fee.

Ask what changed right before it started. Swap the cheap/easy piece first on the 2023 Mercedes-AMG C43 and see if the fault moves. That's the branch I'd chase this week. A shop burned me once by skipping that step. A day of patience here is cheaper than a wrong part. I keep a notes app thread for this now.
