    04 trailblazer 4.2 i6 tranny tune

    I know there are already threads started about this so I apologize, but I cant seem to get a hold of anybody about sending me a solid trans tune or total trans and engine tune for my 04 TB. I have found some that are good but need work im looking for one that is already good to go and proven. Thanks for the help

    The one that came preloaded has been highly tested and proven.

    Post your tune.

    Easy things to start with:
    Reduce engine Tq Mgmt by 50%.
    Reduce shift times by 50%.
    Reduce transmission TM by 50%.
    Increase line pressure by 5%.

    This won't get you all the way there, but it'll wake it up.
