I just installed mine this afternoon. It is a quality product. The components are well worth the cost. Easy to install. I haven't had much chance to test it out yet. Starting is improved, though wasn't a problem. Greatly improved idle, particularly when cold. I don't notice a difference in power or acceleration, though that may come with a little more spark advance. Overall it appears to be worth every penny. A stronger spark will ignite a lees perfect mixture. A less than perfect mixture is the nemesis of BBD carbed Wranglers.
I'll let you know more after the weekend when I have a chance to drive it more. I think you can't go wrong with this product.
