You can certainly always tune your bike better than the factory map does the job, as it has to adhere to emissions requirements etc etc but I would hazard a guess though that the 2014 factory maps (TORS or standard) are likely all you want with OEM air filtration and OEM exhaust headers....messing with the maps for this setup wont gain a great deal.
If you were to fit a Ramair filter and straight through big diameter header and pipes then custom maps all the way for sure...
By all means post up a backup of your R3R 2014 with TORS map though, would be very useful to others who need it....chances are there may be one around somewhere too but I've not seen it.
