Greetings. The more I think about my crossifre (I can't drive it right now, to read the story here's the link: https://www.crossfireforum.org/forum...pic.php?t=1778) the more I am beginning to hate 350Zs. Maybe a mustang/camaro rivalry will develop, who knows? Anyhow, I would like to increase my HP (keeping my costs under 1k) and was doing some research and came across this SpiralMax thing. I was wondering whether anyone has ever used this in their vehicles? Here's the link to get to it: http://www.spiralmax.com/ ). I would truly appreciate whatever feedback I can get on it before dropping any money.
