I hadn't though of that.  As a rev limiter, the factory SyTys 
kill the fuel at 4700 RPM, then turn it back on after it
drops by about 200 rpm...   This makes for sort of a 
mechanical bull imitation, and since it is still under 
significant boost, it is usually accompanied by detonation 
too...   I guess you'd have problems if you cut the ignition
instead...  The exhaust would fill with fuel/air mix...
Not good when the fire returns to the engine...
