The Predator is a great tuner if you can adjust +/- timing maps, fuel injection percentages, etc... I wish my hypertech could do that but then why would I need something like that... I have this problem with messing with cars alot... I cant leave $#!T alone... This Hummer I'm leaving pretty much stock... p.s. I bought this hummer for my wifey... I really want another hummer with a diesel in it... So I'm waiting to get mine when they offer a diesel with a alison 6spd...
