Default Audi fault codes and cutting

I got a 99,5 A4 1.8 turbo quattro. At the moment it has stock ECU, but it boosts to 1.3 bar. Problem: when I push accelerator and when fun should start it just cuts it.. Seems like it cuts of the gas permanently each second, so I go like metalist in a concert.. So, i checked my ECU's faults and it found 3 faults:
#1 17963 charge pressure maximum limit exceeded P1555-35-10 - Intermittent
#2 16487 - Mass Air Flow Sensor (G70): Signal too High P0103 - 35-10 - Intermittent
#3 16806 main catalyst bank 1 efficiency below threshold PP0422 -35-00 (yes, i got Milltek exhaust with no catalyst)

So after that I unplugged my MAF and had a run. But when engine reaches 3000 rpm, its just stops going more (no torque). When im standing in one position MAF shows normal work (2.4g (normal is 1.8-4g I think)).....
So what should I check more? Help plz!
