I am not an expert in this matter, but this is my understanding from using a PST2.
If both cars use the same version of DME, in this case 7.2, then you plug the PST2 in and by following the FSM procedure, you tell the DME it's now controlling a 996 motor and it updates the code. There is no option to make any significant tuning changes using a PST2.

Early prices -- circa 2002/2003 were $7200. A more recent price (I forget the year) had a price (in British currency) listed of £2280.
There seem to be at least one clone of the PST2 available. I saw a reference or two to a Bosch product that in many ways can I guess provide some of the functionality of the PST2 system. More than Durametric's product, but less than the the real PST2.
'course, I've never used the real thing or a clone and I have no idea how to tell one from the other, even if my quick research effort info is correct.
I'll keep my eyes and ears open though.
Thanks for the info.
Sincerely,
Macster.

An hour's "diagnostics" labor even at (my local dealer's rate of $150/hour) cheaper than buying a used PST2.
In one of the articles I sent the OP a shop down in southern CA sorted all this out with the help of a guy in Germany who is an expert on the Porsche Ecus. In fact, if I remember the article this guy even flew over here to ensure the frst one worked ok and to be able to deal with any issues that arose as the car initially driven and used.

I am thinking about putting a '00-'01 DME ME7.2 VarioCam 3.4l engine in an '01 Boxster S (which is also a DME ME7.2 VarioCam engine) and retaining the Boxster's ECU.
Also, any guys out there who have tried this WITHOUT re-flashing the ECU? If that didn't work, what ECU shops have a program that doesn't require a MAF piggy-back box?
