My son bought this car with Mods. It has a 2.9 pulley from ZZP, a ZZP flashed ecu that is for 60# injectors but the car cuts out under boost. In back yard mechanic style I place a piece of tape over the air intake tube just before the MAF to increase airflow past the MAF and it makes a lot more power.. this was just testing so don’t blow me up here. I’m trying to identify the injectors in the car and make sure they are 60#. This would probably explain the P0171 when the tape is not forcing more flow past the MAF. The number on the injector is B205A04771. Any help identifying these would be great.

Just pull the rail there might be another number you can't see, on the LE5 you don't have to disconnect the fuel line from the rail. If you haven't done injectors it's a pretty easy job mechanically, but clean the area around the injectors before pulling and don't screw up the o-rings and lube them before re-install.

Another way would be to have someone just read your tune and check the flow rate calibration table for the injectors.
