Which is best as far as handhelds go? Im waiting for the hypertech to come out for the 02 auto Gts, but its taking longer than expected. Per the company they keep saying 3-4 weeks, but that was 2 months ago. I know that superchips has a hand held programmer and curious as to how good it is. I just might buy that one or diablo if hypertech doesnt hurry up. Anyone having a good experience with superchips.
