Technical Boost leak? MAF gone bad? Help!

[Insanity]

Hello guys, I have a problem with my 1.3 mjt 90hp GP. Many times, while accelerating and while on peak boost, for some reason, the boost will drop for half a second, even less resulting in the car losing power and then boosting again normally. I'm thinking of a boost leak because when the car starts boosting and I let go of the gas, I hear a "swoooossh" sound almost every time. I hear the same exact sound when I get that boost drop spike. But I'm not that sure it's a boost leak because some times the car boost normally without any boost drop spikes.
I'm also thinking it could be a bad maf sensor because I get the p0100 and p0110 error codes when scanning for errors through the obd port and cleaning them does nothing, they come back. But those errors could have appeared after I installed a cold air intake (the boost drop was there even before the cold air intake so I dont think the intake is to blame).

To sum up what could those boost drop spikes be? And why do I get the p0100 and p0110 errors? Any ideas will be gladly appreciated.

There's some readings of the MAF, tubro boost and intake manifold pressure attached to the thread.

Edit: The spike you see in the attached images occurs while in FULL ACCELERATION, I don't let go of the gas pedal.

Update: I installed the original air filter, cleared the codes and they did not come back. It seems the cold air intake was to blame for the fault codes. But I still have the boost leak. Hmmmmm.

Hi, i seem to be having similar symptoms, did you find out what caused your boost leak?
