my understanding is that the difference in HP actually came from using the stage 2 intake piping. The original design was too restrictive for the stage 1 SC to achieve maximum HP. someone more knowledgeable might correct me, but that was how i understood it when i was researching.
they also added the fuel pump voltage stabilizer kit (basically runs thicker wires directly to the fuel pump). this may have helped them tune for a bit more HP as well.
