Default what is wrong with my car??? please help!!!

My car is chipped and righ after i did the air box mod. My boost went back to normal(.5 bar) And no engine light came on or any cluster light. SO Recently i just did the airbox mod. When doing so i drilled extra hole on to the air box for more air. After putting everything back my car's boost went back to 0.5 from 0.8(chipped).i was wondering could it be my by pass valve(leaking or dead)? What can be wrong. everything seems right no cluster light went off or any problem with driving. Can the extra hole mess up my MAf sensorand make me go to safety boost?(could that be it).. How do i tell if my by pass valve is bad?
Thanks alot.....need so help bad!!
THANKS

Check the connection to the Boost frequency valve.

Default I don't know what the air box "MOD" is, but it sounds like you drilled holes in the

air box. Did you hit the mass air sensor when you did this? Or if you took the box out did you re-connect all the sensors that you unplugged?

It meters and controlls, via the ecu, the ammount of boost your turbo gets.
