Should I perform LN IMS update before selling like new boxster?

The answer is yes.

Now, why would a Porsche Technician come to enthusiasts for advice. Stinky stinky stinky.

Sounds like this should be in the classifieds.

But to answer your question, if you're a tech and already in there, no, I wouldn't touch it. You assume liability if you do. If it isn't broken on something you want to sell, DON'T touch it.

Everybody knows that.
