    as the title says, im hoping a few people would have a 4.3l EFI tune they would like to share. the shop i go through has a lot of of tunes for 4.8+ but this is the first 4.3 hes done. hoping to get a few tunes from people and then maybe take what we want out of them.

    trimmed butterfly

    modded air box
    electric injectors
    shortened exhaust with flow master
