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
