So I've upgraded my

intake fuel pump (deatsch weeks 265 l),
Cp-e HPFP
PTP relief valve

How do I tune for the hardware upgrades, I'm new to VT and tuning .

You can increase the requested fuel pressures but no real tuning measures are required. I answered your cut issue on the other thread.
Fuel cut has nothing to do with fuel delivery, it is a safety feature contained within the tune.

I think that the stock fueling system (with just a simple HPFP intenals upgrade) is good for sustaining about 380-400g/s of air flow. This is around 400-420BHP I think. So all these upgrades are for your peace of mind, because at 400whp you will already be past the point of the stock engine internals comfort. So if you still have the stock turbo on your car start tuning and monitoring for other parameters such as load, BAT, spikes of any kind (load/boost), severe knock, and so on.

Good luck!
