harley,

don't quote me on this, but i'm pretty sure that a true dual system will not net any real performance advantages. i know on an FI engine (turbo or s/c) it can help reduce back pressure and you may see some gains, but i dont think on an N/A setup.

Like I said, don't quote me on that. There are many people who are more knwoledgeable on the subject than I am. I'm sure someone can confirm or denouce this for us soon.
