Thats old tech... these days it's electronic wastegate linked to knock sensors... the sensors pick up pretetonation pulses long before they can damage the engine and crack the wastegate to lower boost on intake, Like wideband O2 sensors keeping fueling just on clean burn, knock sensors keep boost to maximum possible below grenade point.,
More common in hot rods is raising the compression to barely safe on pump gas, and running lots of boost, for both racing power, and limp home cruising. ( this takes self control. It's easy to build an engine that you can wreck if you get stupid )
Stick anything in the tank and the computer will work out how much boost to cram in as well as how much fuel to match that compressed air.
