Yes PU was the one that prompted my post but over the past couple of months I had struggled with MOST, IMS, PCM and a couple things in threads about the engine that I can't recall now.

At a recent meet, I did even hear another newbie comment that it had taken them a little while to realise what OPC stood for. I'm not that bad (!) but what is obvious after a while is not necessarily obvious to someone new to Porsches and this forum.

Surprised

Crikey. I only know about a quarter of these, about a quarter I have seen but don't know and I haven't even come across the other half of them! Question

Clearly I (and perhaps others) are in need of education.

GT4, over to you to do what you do best and share your wisdom...

The fourth category of the FIA GT Championship: Gran Turismo 4 (more privateers, behind GT3, GT2, GT1).

Or for me, a slightly-more-power-than-a-Carrera, but less-power-than-a-GT3, GT3-lookey-likey with 4WD.

A 997 GT4, yesterday:

FWIW (= for what it's worth), PET is an abbreviation of PET-System, or Porsche Ersatzteile-System, Porsche's spare parts listing system.

My personal favourite internet forum abbreviation is RTFM = Read the Manual. Very Happy

Thanks GT4. I would have put money on it being you who 'filled in the blanks'. worship

Note to Moderators - perhaps this should be a sticky in the NEWBIE section of the forum or FAQs as well as the Buying Advice section. Many of the terms are used in threads after a newbie has bought and found their way to the forum so wouldn't necessariy look in the 'Buying advice ...range comparison section'. Just a suggerstion since I didn't find the original thread when I was looking - but maybe that's just my incompetence.
