"The scramble boost feature on the SBC-iD is a unique one, shared with Blitz's DSBC spec R. Rather than having a button or switch to toggle a different boost level for some set amount of time, the system activates every time you go from vacuum to boost. The unit scrambles to a different channel where the boost can either be raised or lowered. Once scramble times out, you need to drop into vacuum again to reactivate the scramble mode. Blitz claims this system was designed for a circuit-racing environment. We don't get it. Luckily it can be disabled."
