The SC won't have an overboost safety cutout switch like the 930 does.

On the 930 the ignition timing is advanced on Vacuum only. It does not actually sense boost to retard the timing. In other words the timing is retarded even on light throttle.

Do it if you want but the transmission is what put me off increasing power in my 3.2 so I bought a 930 instead.
