      Surpassed my expectations. I was unsure how much a DNK tune would actually do for my bike that only had an x-pipe fitted. The sound change alone is worth it. Music. The added performance, responsiveness and in general a wake up to the bike was a superb bonus.

      So happy find shop with map available and expertise after sale. I don’t have near dyno and one which is is very expensive, the only option is to use ready tested and developed map. Map was matched with my bike modifications, also revised during first 14 days when I submitted additional upgraded and tweaks to the map, as a advice be specific and know you bike readings before submitting and trust DNK team replay, they are professionals in this field. Also make sure before upgrading map your bike 100% service healthy before applying map, its very important. Now my motorcycle so much responsive, like new just on steroids, fuel economy improved unless I will ride 100% throttle :D.

      Excellent upgrade to my Street Twin. Really noticeable difference. Definitely worth the money.
