Thanks Robb. I'm not sure the rev extend really does much other than remove the annoying cut out when you have taken the rpm's too far to begin with. I guess depending on your build, it may come more into play. You might think about that. With this setup, you really need to shift at about 5500 anyway to get back into the meat of the curve. I don't regret it, but it's not really all that useful for what I did here.
