I just put on my new ignition last night and man, i'm impresssed. It got rid of this annoying slight lag i would get and the rev limiter is really cool. You can just dial it to what you want and even if you floor it the RPM's will stay at the preset setting.....cool! I also got the matched coil to go along with her. I mounted the unit right next to my CAI so it was no problem. Plus you can still use your stock tach wwith no additional hookups. Just thought i'd comment
