Exclamation HELP!!!!! Car keeps throwing overboost code

So i have a 14 Gen coupe 2.0T A/T. Car has intake, turboback exhaust, and bov. When going WOT car gets turbo overspeed code. When just crusing and not hitting full boost car seems to run fine. Replaced the wastegate thinking that is what it was and that didnt change anything. Anyone can help me with this? Does wastegate need to be adjusted or could it be the 02 sensors??

What BOV do you have? Connected where?

Also, did you unplug the battery and let it sit?

Connect your BOV to manifold pressure instead. Sounds like the BOV might not be going off fast enough with the extra airflow of your turbo since you removed the cat. This results in the computer expecting less air pressure vs what is in the manifold still.

didn't realize that this is on a BK2.

disconnect the connector at the waste gate actuator, and plug it back in.

Also, disconnect the battery for an hour, and connect it back.
