I called Roe Racing last week, and they are out of them till mid this week. I will say that Roe was very helpful, and they will answer any questions that you have. They will program the cards for you if you would like. They were telling me that with different mods, that they have seen up to a 60+ hp gain. Mine is on the way soon.(hopefully sometime this week) He was saying that it is not to hard to install, just as long as you are not color blind. They send all of the hardware that you will need... Give them a call, they are good people..hope that helps
