You're kidding right?
You know enough to have a supercharged Bullitt with gears, but don't know that Bully Dog makes diesel stuff, and hypertech is junk?
With a supercharger, you should shouldn't be getting stuff like that anyways, you should link up with a professional tuner and use whatever he tunes with, most likely either SCT or Diablo. Bad things happen with superchargers and generic crappy tuners.
