Read on their site that due to increased air flow a re-map may be required. Let us know how it works out for you. I have a 2015 also and will be ready for an air filter this fall.
Yes remap will help. don't know who flashes ECUs for the Versys. Normally the best place to go is a local shop that has a dyno (you get to take the rear wheel HP map home and put it on the wall next to your Farrah Fawcett poster...)
