• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Are they the same or ..??



Some cars use BCM communications, some don't. Wiring to the PCM may be different between years and different options I really don't know wich does and wich does not. It's never a good idea to put a PCM in your car that doesn't belong.


And Any ''chips'' that you will find will be a compleate wast of you're time and money and do nothing for you're car.


If you're looking for performance go with a tuned PCM
 
GM has done so much changing around with the new body style (04+) that I'm not sure. More than likely it is the same, but I'm not 100% sure. All I know is with the older body style any PCM from 98-02 will work in any 98-02.
 
I have a 07 and they do not make a tune for it. But I have been told and read where people have been putting the 05 into the 07 and its working. The only problem is the fuel reads wrong. But it was the supercharged ones not the SE.
 
well the chip i was looking at was on summit and jet makes them for the computers. i was thiking of just taking it to a speed shop and letting them deal with it
 


it takes forever to get to 110 in a stock grand prix. how are you worried about going faster at this point?
 
Just stay away from anything you have to add to you're car. The only thing bennefictial to these cars are to tune the pcm electronicly.
