I received both the email and letter. Since it is voluntary, I've decided to voluntarily not do it! My sport + works well on the track, just the way it is!
I think the word “voluntary” means that Porsche agreed to the recall without requiring an order from the NTHSB. It is not “voluntary” for the unfortunate owners who live in California who have no choice if they wish to register their cars. But, I agree with you. I am not having it done either but live in a location without emission testing. The lack of any information available concerning this recall and tune is deafening.
This is misinformation regarding CA cars. I moved to CA and registered my C2S a few months ago without needing the update. No questions asked. It's a non-issue.
