You should get the Dobeck because if you don't you will end up running lean and you could damage the engine.

i have a hmf slip-on, i have the power commander. i tried riding it down the street before i put the pc on but it ran like crap. in my situation it was needed. some people have run just slip-ons without controllers and i have been fine. just keep an eye on the plug.

If you have a good Yamaha dealer around, he should be able to adjust the existing controller so it will be fine with the HMF, most don't know it, but my dealer did, and mine runs great.
