re-calibrate gas gauge

[Anker]

If you want to work on your Boxster you need the right tools. There's nothing that's more expensive than delivering a botched repair job to a delership. Trust me, I have been there.

If you want a less expensive code reader that reads Porsche codes you cal also buy an Autel, but it can't do everything the Durametric can, and its still a couple of hundred $.

Try to go to your local autoparts store and ask them if they ha a code reader that you can borrow, and whether it can read Porsche-specific codes.
