    2004 Deville PCM

    I can't trap an answer ... hopefully I'll catch one soon.

    Is my 2004 Deville fully tunable, or, does it suffer from the same issues that kept 98-03 PCMs from being tunable?

    In other words, can I do something dumb, like, add a turbo, and then tune the PCM to deal with it?

    If the answer is no, has anyone ever considered using a piggyback to bypass the PCM? How do the sandrailers use these motors?

    Ion at Mad Tuner is your guy for this PCM
    We have the files for this, but I would like to get this over to Ion.

    ----------

    Even if we tune this I would need Ion to help out on the check sum.

    Hi. Sorry for the delay on an answer. Ion is in Chicago, yes? So I would need to travel to Chicago?
