I advanced my timing automatically with a billet PVL flywheel, the rare earth magnet comes set at 28-degrees. I then added a 7.2-degree advance key for 35.2-degrees total. At high rpm's it runs like a raped ape, but remember that a standard ignition coil will start retarding the timing at high rpm. My hi-perf coil has the resistors disabled so it won't do that.
