I want to get rid of the intake flap system on some EA113 TFSI cars.
Just disconnecting the actuator and leaving flap open (or remove) is throwing codes and can cause cold start issue.

Has someone tune it out and adjusted the tune to avoid cold start issues?

CAEB is an EA888 engine, not EA113. Why are you trying to remove the flaps? They're not a restriction on the EA888 as they lie flat when open.

I don’t get why anybody removes  these flaps from this engine? They’re needed for swirreling the air to help mix the fuel in the cylinder? Or am not not thinking straight?

Anyone ever measured airflow vs boost or power on dyno in a EA113? I cant believe there is a measurable difference...

It's very easy to get it to cold start like stock. Disabling fault codes isn't enough, you need to kill the LBK function.
