With the 06 GT Vert I just bought came two programmers - a Diablosport Predator and a Hypertech Power Programer III. What the difference in these? Scrolling through the threads I am getting the impression that these are old technology?, but I assume these are still useable? What the best of the two? The car is basically stock - a cold air intake and a Cherry Bomb ( I'm assuming catback ) exhaust.
