Even at wide open throttle, there is vacuum in the intake.
The intake has an air filter, throttle body butterfly, MAF and MAP sensors, fuel injectors, valves, all running thru a tube. It causes resistance when moving a large volume of air. Then if you have boost, add an air pump and intercooler resistance to the intake.
