Pretty easy: boost pressure difference to high, maybe because of bad tune => check PID an an tune it.

I think it is not only wrong MAF or big turbo. We don`t know AFR, EGT, or basic details of sw. |

It is running TTE480, upgrade hpfp, and Lpfp, injectors from AKS, which should been around 15 % more flow than rs3. 165 bar fuel return valve. 4 Bar mapsensor, 200 bar fuelsensor , and upgrade chargecooler. |

These upgrade turbos produce most likely a lot of backpressure, maybe this part from your knock problem. I think tte use stock manifold?
