You need to check out the Best Kept Secret in Racing! If you are having to compete against a Davis device then TRACS can help.  TRACS reduces a MSD®Ignition systems output by 25%, which decreases engine performance by 10 to 12 percent. Interested?  http://www.techwestracing.com/page20.html
From 10/19/12 to 10/31/12 you can purchase two TRACS devices for $275 each, if you need just one $350.00 each. Thank you for taking the time to read this post.
