what i like about the superchip one and also with what i am reading about the SMARTY CATCHER one... is that you can run them without worrying about throwing codes or putting more stress and crap on your stock drivetrain if you dont want..... well i guess if you put SMARTY on #8 or #9 you would... but you have 0-4 that are performance increases without stressing drivetrain.
