    Is it possible to use 04-05 Grand Prix PCM for 05-07 Lacrosse?

    Possible that the computer can be used but it's likely to need a dealership scan tool flashed with a buick lacrosse file on it.

    I have a strong feeling that VATS and dash/vehicle functions will not work right using a grand prix calibration.
