Just another X-File again as i dont know why suddenly my knock counts rocket???

I didnt do anything and have done a boost leak test with minimal leak observed.

- Didnt change anything
- What i did so far before the rocket knock is, ive removed the air filter profec b II controller and direct bypass to the electronic boost controller.
Noticed turbo response reduce.
- Have plug back the air filter with confirmed correct position.

Anyway of knowing a weak fuel pump and an additional relay required for the fuel pump?
