Recently posted that I had purchased a Pro Tuner fuel controller from Dale Walker at Holeshot.com for my '14 N1K and it did not work. After talking with Dale he got me in touch with Matt at Dobeck Performance who makes the controller. Had me send it to them to be "re-pinned", got it back, and after installation it fired right up. After putting about 100 miles on it I have to say it is a definite improvement. Have Akrapovic headers with stock mufflers and a K&N filter on the bike. The engine seems to run smoother if that makes sense. Good low end response with more power over 6k rpm and it feels like a better bike. After the initial disappointment Dale took care of me and I would highly recommend dealing with Holeshot.
