Did you read what you wrote? Cylinder pressure is strongly affected by boost (along with ignition timing, exhaust system, compression, ...) and unit of boost is psi which happens to be a pressure unit. Boost is not a concept, it is a measured engine variable, go ahead put a gauge in your car ... it is also available with a cheap OBDII device. There is a MAP sensor to measure that "vague concept".
