    I thought I remembered someone saying they had good luck with the cobra tables (Grady?). What is involved with swapping over to a GT, and more important, how do i actually do it with the tweecer? thanks!

    Back in the day when I was more involved with the self tunning community
    you could find bunches of 94-95 GT folk who moved over to the j4j1

    The folk who had the most to gain had these basic similarities

    The usual h/c/i
    24# or larger sized inj's
    stick trans

    Not all that hard to switch really :)

    You start off with a known clean untouched j4j1 file
    Load in your inj values if different than 24's
    Load in your meters t curve
    Upload the modded file to the pcm
    Try it out for size :D
