2017 Porsche 911 — conservative tune feels great — what should I log?

BoxerDIYerCommunity StarterJan 23, 20262017 Porsche 911 Carrera SCharlotte

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?

I parked the 2017 Porsche 911 and wrote down what I already tested so I'm not repeating myself. Might be overthinking it, but I'd rather overthink than overspend.

Owner notes beat generic advice here. On the 2017 Porsche 911 in Charlotte, 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. Was this after sitting overnight? Wrote this up on my lunch break.

Don't overfit one forum story to your car. If it still isn't clear on the 2017 Porsche 911, a specialist hour can be cheaper than another round of parts. That's where I'd start. Post the numbers (or the code) and people can get more specific. I'm in no rush to be a hero on it.

I hear you, though I'd still want a second check. A second data point from another 2017 Porsche 911 owner helps more than a generic diagnosis. That's where I'd start. Have you gotten a second quote in writing? Might be overthinking it, but I'd rather overthink than overspend.

Useful. I'll report back after I verify that on my 2017 Porsche 911. If this is nothing, great. I want that in data.
