I have a 2012 Speed that I purchased used with about 2500 miles on it. The first thing I noticed with the slight hesitation/engine vibration from anything below 3k rpms. I thought there was something wrong with the engine, but the tech said the factory map runs lean for emissions purposes.
Once I put the Arrow high mounts on and loaded up the tune with Tunecu, it completely eliminated all hesitation down low and the bike now rides super smooth!
