I have a similar PPS dated from 2020, no engine/trans number. I believe the PCTC is a in-dealer inspection that’s big $$$.

From Porsche website:
What is the difference between the Porsche Classic Technical Certificate and the Porsche Production Specification?
The Porsche Classic Technical Certificate and the Porsche Production Specification are both certificates which can be ordered for your classic Porsche. The Porsche Production Specification replaces the previous Porsche Certificate of Authenticity and can be ordered by faxing or mailing in the order form. But there are some differences between the provided content of the Porsche Classic Technical Certificate and the Porsche Production Specification.
