Not boosting properly

[shaun8215]

Hi. As it say above my car is not boosting properly but only when it is warm it dose not boost. When i first start driving it in the mornings the car boost fine 0.9lb but 2 mins later its not and only boost 0.5lb which you can fill the differents, is that putting the car in to limp mode? But i spoke to a friend and he said remove my air box and see if that makes a diffenents which its has and it always boost now but with no air filter so dose that mean my air flow switch is gone??

thanks shaun

Its is just a standard filter and box. But did check the air filter and box for dirt but looks clean.
