330ci AA stg1 c38 problems

Hello everyone

I need a help with this FI guys

A friend just installed the stage1 kit on his 330. We follow the instructions from AA installation manual, but when we try to start the car we have several problems.
Running the car with the MAF sensor connector causes to have a rough idle, misfires and the mixture seems to be very rich.
We have tried 4 different maf sensors, It's very strange because if we disconnect the maf sensor the idle seems.... to be normal

The DME shows no errors and the car was perfectly fine before the install.

I assume you already sent the ECU back to Active to get it tuned.

MAF, Cat clogged, 02 sensor, or injectors are not seated properly so start with those.
