IM wanting to buy one also and would like to hear some results.

It increases velocity, but reduces flow. Reducing flow = bad!

You want to flow as much air into the intake as possible, not as fast as possible.

Just like the "Tornado" or whatever it was called, it is BS.

If you want something that really works, get your TB ported by Bauer. I love mine, and it actually works

It increases the velocity of the money going out of your wallet.

all it accomplishes is covers the idle and pcv inlets in the tb mouth.. you can do this yourself with some epoxy putty, sandpaper and a drill and not decrease the size of the tb opening overall.

i here you all...
i really do...
but my question is have any of you seen dyno results????
i was thinking the same thing as you till i looked closer at the design....
the smallest opening in the tb stock is still the smallest part after the part....
so how can it be a restriction???
