Ebay 60mm turbo 38mm wastegate siemens deka 830s e85 fmic custom big turbo file to support said setup
When it sees any sort of boost it falls on its face, struggles to make any sort of boost and sometimes has a rough idle. I've checked for vacuum leaks

When did this start? Was any work done prior to the issue? Have you scanned for codes?
