I ride with someone that has one. Mine is stock other than a par head and clutching. (Much better than stock). The stage 4 slp kit will pull me quite handily everytime. Now he did spend alot of time getting this thing to run right up here in Alaska. Our air is different up here and we have always had those issues and are on our own to figure it out with no help from the place that makes and sells kits since they don't run in our environment. Odds are down there the tuning will be much simpler. Once setup, it was pretty much a pull rope and go. But for the kit of money that stage 4 kit runs, I think I would go turbo 1st. Other than a 100' drag race, the kit doesnt stand a chance running against even a mild turbo sled. Night and day.
