I am sure that what dragon fire has is a good product, The research that i have done recently has concluded that the RZR runs rich at idle and leans out from the middle to top end as the rpm climes, I do not know there system but i know you need to talk with them and see how there fuel curve works and I am sure you will need a fuel controller to set proper fuel mapping for the engine after there system is installed, Dynos work well in a controlled environment but do not correct for your current altitude and temperature at the time you are riding and i would add a wide band AF gauge to watch what the engine needs, the unit from dragon fire will add a O2 sensor to make the corrections that a modern automobile has on there modern computers in regards to what comes out of the exhaust that the current UTV systems do not have at this point.
