as i said, boost is controlled via wastegate actuator. increase in boost is like, too small for us to see on the boost meter. yes, the intake temp decreases hence forcing the intake air flow to become denser hence increment in the boost sumone here mentioned. but, u have to remember the boost level is still controlled by the actuator, dis is the safe-key for the engine to live longer. and as the map sense dis sudden increment in boost from the turbine, boost cut occurs and boost is forced to a near constant level.
by saying the boost readouts doesnt change, i meant dat the increment cant be seen. its not a big factor imo, not in malaysia neway :) u'll find dat if u r in colder region, just fitting a FMIC gives a lot of boost cut, which u really dont want neway, rite?
