I was looking at slp's stage 4 kit for the 800 cfi. Is anybody running this kit? I like the thought of 167 hp instead of the reduced hp with the new update that we got.
Any time you can get away from the factory EPA compliant tuning you will gain a lot, let alone some mods on top. The SLP stuff runs and as a complete package are hard to beat as a pull and go sled running pump fuel. Carls, Fastrax and SLP all have proven packages for the 800 CFI. They all also have different characteristics.
