I am running the 95 OBDI Bonneville PCM on my 3800 Series II Turbo and can tell you that it works relatively well. There are a few minor quarks that will get cleaned up once I move the MAF sensor to just before the throttle body (I am running one between the turbo and air filter).
I stayed with the 95 PCM for 3 main reasons. 1) Because I don't need or want all that extra wiring and OBDII mandated crap. 2) DHP wants WAY TOO MUCH money to reprogram an OBDII PCM, furthermore they would not do what I WANTED done, they would onlyo do the things THEY WANTED to do. 3) The biggest reason: you can change out chips at the track for race gas, different boost settings, etc.
Email me if you have any more questions, I would be happy to share all of my info and experience with what I have done. I also do custom chips for the 95 Bonne PCM as well for a very cheap price.
