    Umm, quick question. Why is my PCM marked with an 'L67' in the upper right corner above the Delphi logo? Isn't that the GTP motor- or are all 97-03 PCMs marked the same?

    My PCM was never marked L67.

    If you have an L67 PCM...it won't work with your GT.

    Unless it's flashed for the right OSID, which isn't necessarily what is marked on it.
    I drink..so consider that when reading my posts.

    I just thought it was odd. I checked a friend's Blazer and it said 'C-somethingorother', didn't check the SE 'cause it's still in the airbox. Is anyone else's PCM marked with a different number?
