What computer code? (Certain codes are known winners & losers) If you search there's a huge thread about it.
I'd go with Superchips personally over Diablo. Even before I heard some Diablo horror stories.
However either is pretty much a crap shoot; with Superchips having the edge in experience & major edge in code coverage.
IMO unless you have an ATX (or a known winner code) it's not a good first mod.
