Re: 997 PSE Retrofit
I picked up my 2005 in October 2004. I had PSE retrofitted six months later. I think RC picked up his 2005 as soon as it came out, so he had one of the earliest ones. I think he too had PSE retrofitted. And I've never heard that there was a cut-off (or cut-on) date for PSE retrofit. So, no, to my knowledge, such a thing does not exist.
