It wont happen, Im sorry to tell you that it's just not do-able at this point in time. I was in your exact shoes, and I dealt with Will on it, he sent me a pcm that was Delphi and the car wouldnt even start, just cranking and cranking. He reverse tested it by putting an AC delco pcm in his 2004 with a Delphi stock, and again the car wouldnt start.
I even contacted a few GM resources and searched all over, it's just something that cant be done right now.
I traded mine for an 04 comp G, lol... that's the only real way to do it. Will suggested to me that maybe if you switched out all of the other computer modules with a Delphi one, that could help in theory.
