Now this is an interesting subject. Dalite has several good points, and I can address several of them. The Stage 1 controller is an NGC3 module, common with all the 04 Turbos. It is however a different software set, specifially for MPP. And we don't let the dealers flash it for the very reason you said, lest it become a free upgrade. Don't know who told you different, sorry you were misled. Also note that there was no CARB certification (which may change), which may tell you something about the OBD and it's pickyness with respect to additional hardware modifications beyond stock. Not to say that it wouldn't pass a sniffer with the aftertreatment in place (and I think several have already tried successfully), just that there are other items in the regulation besides passing a sniffer.
As to how much we are required by the EPA to reveal how our code works is another story. That's propietary just like any other kind of software, and we don't have to reveal source code if we don't want to. Self-diagnostics is not the same as core engine functions, the former of which the EPA is really interested in.
Please keep up on this subject. I can't talk about certain things, and you can guess what kind of things are proprietary.

First, let me say that I do appreciate your candor. It is good for all of us on the forum to get a chance to wade through the rumors and get to the meat of the issues.
I had suspected that the dealer could physically do the flash, but it would cross over intellectual property/rights boundaries, and not be allowed.
Here is where UniqTwin / TurboG told me that it wasn't possible for the dealer to flash the Stage I software in the Stock 2004 PCM:

To her credit, she is one sharp cookie, and she was probably saying the same thing, but in far less words. It was probably mere coincidental that it followed one of my posts concerning the similarities between the Stage I PCM and the stock 2004 one. It is good to at least put that theory aside, and to be able to understand the reasoning behind it. I can understand that and respect it...
I have followed the thread where Stage I passed the smog check; both the data link and the probe. OBDIII will do away with the smog check in favor of a wireless link that will pick up the current level of compliance of a car as it passes under a transponder. I think the theoretical traffic load was something like 100 cars passing by at 50+ MPH (But I could be wrong).
Since the OBD system is based on emission compliance, it would already have a record of what is coming out the tailpipe, a far more accurate one. NOX is a percentage of misfire; the PCM can not only tell the overall percentage; it can tell the percentage of each cylinder, and a basic duty cycle of each within that percentage.
For each offending gas or pollution level that leaves the tailpipe, the reason it exists is stored in the PCM. OBDIII would simply mail a letter of non-compliance to the name associated with the VIN number that is transmited along with the OBD info. After a specified period allowed for repair, if that VIN shows up out of compliance again, a fine comes in the mail.
Personally, I don't like the privacy intrusiveness of the OBDIII proposal, but it does go far in demonstrating the level of detail that the current OBDII is capable of reporting.

BJ@DCX.COMs forwarded post on the SRT-4 forum about the pending CARB approval, as well as the rewriting of the MPP Warranty. It is all good.
On the EPA and the code, not what I was referring to. It is a SAE standard, EPA is involved, but it covers the requirement that the diag link be made standard so it will allow a universal API to access it for both data logging and flash
