You'll be fairly limited using just an RSA delete as it has the stock software. Probably good to about 14psi due to the limitations on target airflow. There's also the physical limit to the boost target at 1.28bar that needs patching too.
I've attached the basic RSA bypass in a zip. You would need to build your own 0da file to flash on top of this, just be aware you need to correct the checksum and ECM3 if you make changes.
