Finally got mine built and tuned. It's incredible. Kit was ordered last year and I had originally planned to fit it myself, however it ended up being a much bigger and complex job than I had the ability to complete. Got a crew nearby to take on the build, they had some issues with tuning, went through many many plugs and eventually melted a piston or two. TTS shipped a new set out and eventually we got it all sorted.
Final Dyno was 306hp. The guys that built the bike used the TTS tune as a base map.
If you haven't ordered a kit, do it. Turns the bike into an even bigger monster.
