SpiralMax?

[mistahmoogle]

Anybody out there have this and can vouch for it's horsepower and torque gains? Where in the powerband do you get the most improvement? Still kind of skeptical to see how much horsepower something so simple could add to a DOHC 4-banger. Here's the link - <A HREF="http://www.spiralmax.com" TARGET=_blank>http://www.spiralmax.com</A> <P>Oh and on a completely unrelated note, how do you access the archives? Sorry if it sounds stupid, but I can't find a link; all I can do is set it to show all posts.<P>Thanks!
