    you can just buy them and install yourself then send your old one back for the core charge.

    3800performance.com has them.


    What kind of mods do you have on your car?

    Getting a tuned PCM before certain mods may make your car run very rich and not perform well.

    I wouldn't recommend tuning it yourself, since there's a lot to tuning that you can mess up on and break stuff. Also it's not cost effective since you'll need HP tuners, a laptop and a wideband.

    I would recommend getting a dyno or track tune by a professional with a good reputation to get the most out of the tune.

    Word of advice, never use a tuner that uses the factory oxygen sensors. This is because they are narrow band O2 sensors are only made to read 14.7 afr.
    At wide open throttle the AFR should be between 12.7 and 11.00 depending on power adders and boost, this range is way outside of what factory O2 sensor can read.

    If there's no reputable tuners in your area a mail order tune would be your next best bet.

    Yes, putting a tuned PCM in is essentially plug and play. There are several places to buy them from, and they all ask your input as to how it is programmed or to fit any mods you might have. The only thing to be aware of is most tuners suggest/assume you are using a 180F T-stat.

    The wbodystore and intense-racing both have great PCMs.
