Awesome Upgrade!
I installed this kit onto my '15 Speedmaster along with the dyno power commander. The power commander came with instructions and there's also an installation video on youtube. I'm a "hands on" type so while the install was fairly easy I had no idea how to properly map the fuel injection. After finding no maps online and having resigned myself to bringing it to get tuned I called British Customs. I practically clicked my heels together when they told me they have a map for this upgrade! While it may not work for every bike at every elevation its a starting point for anyone who doesn't want to pay someone else for something they can do themselves.
The pipes sound amazing!! The bike runs amazing!!
I'm even gonna play around to try and get a little more highway mileage out of it. Next is the crank shaft upgrade!
