    I have one of these on my 2009 FLHT and about 16,000 miles on the motorcycle sice installing and have not had any problems with it.
    I am in the process of changing my exhaust to a D&D 2 into 1 and will just download that information into the ECM and ride the motorcycle and it will re-tune itself.
    No More Expensive Dyno Time every time you change a engine part.

    Hey, Nicker.I believe if you check with NHTSA the conclusion is that about99% were caused by cages who do not know how to drive, uh the brake is on the left da bigger pedal !

    Have one on my 08 Road King, works as advertised, love it…. The multiple map thing would be nice when riding in high-heat traffic- richen up the mix a bit to cool it off a bit, hmm…

    On the Toyota thing – try 100%. By the way, an excellent example of media manipulation. One day – magically – no more Toyota stories. Why? Did all the Toyota’s “fix” themselves? Or did the public get wind that tha potential legal lottery had been shut down?

    Same thing with the Firestone/Explorer stories – just went away after being all you heard about for months.

    We as a country have gone collectively nuts.

    Don’t know the specifics of the Toyota “problem,” just what was in the news.

    Only reason i ask…… if a scooter exhibited the same occasional unsolicited power surge that my Chrysler SUV produces at a certain throttle position, although very slight, the effect could be something less than confidence building….
