HELP… Cant figure it out

I installed a JB4 a few days ago on my 08 135i auto an all was fine until yesterday. It Started throwing codes, jumping from map5 to map4. They somehow cleared themselves an the car runs fine again. Then today the service light came on an the car would shake like hell if I pushed the gas. After about 2 min of this the light went off an the car runs fine again??????????????

Any insight would be GREATLY appreciated.
