1987 Porsche 911 — conservative tune feels great — what should I log?

UsedCarMom938Community StarterSep 2, 20261987 Porsche 911 Carrera 3.2Baltimore

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? Mostly looking for the right next step.

Checked the easy stuff on the 1987 Porsche 911 and found one clue worth chasing before I book a shop. I'd rather pay for diagnosis than a second guess-repair.

This is usually cheaper to test than to guess. Get a real battery/charging test on the 1987 Porsche 911, not just resting voltage, before blaming a module. Don't erase codes until someone who can help has seen them. Not gospel, but it saved me a headache. I already checked the easy fluid levels.

There is early surface rust on brackets, fasteners and seams underneath, but nothing structural. For a salt-belt car, what treatment slows it down without creating a hard coating that traps moisture?
