Question ECU part numbers - check for Stage One?

My 2004 Touring (auto, turbo lite) had the ECU replaced long before I got it (according to scanty service docs that came with the car).

But the car has stellar performance, and lately I am beginning to wonder if maybe it's had the Stage 1 computer installed. Is there an easy way to check for that? I have an UltraGauge but no other readers...

If an original Stage 1 PCM or if one flashed by Flight Systems, it will have the Stage 1 label on it.

Here's a photo of a 2005 Auto Stage 1:



If you cannot tell from that, I have a complete list of Stage 1 numbers at home. It's different than you will likely find on the internet. Many lists have the flash part number and not the number on the front of the PCM itself.

Okay...

At least one of the part numbers for the 2004 Auto Stage 1 is P4510630AB. You will have to physically look on the front of the PCM to see this number. That will most likely NOT be the number that the OBDII scanner shows you. The scanner is going to show you the flash number.

And if your boost is still controlled by the PCM and your boost gauge reads like mine, t'ain't likely no stock PCM.
