The LED guy....
Hey guys I was wondering if anyone knew if I would be able to run and 04-05 PCM in my 2008 grand prix. The only reason i am thinking about doing this is because I have heard that the 08 PCM's are untuneable. Any info would be great. Thanks in advance
 


AFAIK, the only issue is that one of the years (07 i think) uses a different signal for the fuel tank an it reads backwards.

also the 08 gxp is not swapable as its an e67 pcm and different from the rest of the w-body line up.
