Sounds like you may have knocked one of your turbo pipes off if your getting masses of boost which could also be causing an air leak after the maf. ECU reads the amount of air flowing past the maf and adds the correct amount of fuel to the engine, if the air is leaking after the maf then it wont be adding the correct amount of fuel. If the pipe that comes off the bottom of the turbo to the turbo control valve/boost control solenoid has come off or split it will be leaking there and overboosting as it uses the pressure from the turbo to open the wastegate and control the boost.
With the MAF disconnected the ecu will revert to a base fueling map as it can no longer measure the air passing the maf
