FP comes with tuning instructions where DJ does not. The DJ kit is just a generic setup where as the FP kit is more markeket for tuning to your geographical area. For example a guy in florida will not have the same setup as I would as the air temperature, elevation and everything are much different. FP give you insturctions on how to tune for this. But I havent had a chance to tune my carbs, so right now its only on 4th clip on the needles and 118 main. But after test riding i need a much richer setup. Since im posted to ontario and my bike is in new brunswick, I havent done any test and tune.
